Why Lord Frost wants a Thatcher revival

And do you think it is possible to continue to make the case for Brexit? Absolutely it is. The problems Liz was facing, the problems. Rissue was facing, the problems of current governments facing are the same problems. The state is too big, it's doing too much. We're running a massive deficit. But you personally believe that climate change is real. David, it's immensely good to see you. Why in a sense of you decided to take over the running of possibly the best-known economic think tank in the country? Yeah, well I'm glad you say that Robert, I think it is and obviously we've been here for 70 years and have a strong reputation I think. Lots of well-known people have been through the IA doors as interns or writers or contributors at some point and it's a really strong part of the scene. I mean I wanted to do it really because we seem to be in a phase of British politics where we're in the middle of a government that almost certainly isn't going to be an election for some time yet. What needs to be done is fight the battle of ideas and one of the problems the countries had is that we have not politicians have not opinion-formers have generally not made the case for free markets and freedom really as strong as they ought to have. Over the last 20 years we've seen the state grow and grow the government reach grow and grow regulation expand, government spending expand and we're running up against the buffers now on all this and so what I want to do and why I'm here as opposed to politics is to fight that battle of ideas and get involved in the debate. So can I ask on that then because I'm really interested by this idea of you know you're a free marketer you think there should be low taxation, low regulation and things like that. I'm a business owner and you know I'm all for lower taxes to improve growth but how do you start that process off without spooking the market? It's like how do you improve your compare for them because as we saw with Liz Truss who I know is you know kind of a close friend of the I, yeah it caused carnage didn't it that sense of how are we going to pay for these little taxes so I can understand the long-term argument of it in terms of bringing in improving growth and productivity and that brings in the tax revenues but how did you start it off without causing market carnage. And can I just sort of slightly add to that because you did say that you think it's, it's got a stronger reputation than the IA. I mean I would slightly caveat that. I mean when I was a cub reporter I would see IA people in particularly the absolutely lovely Ralph Harris you know quite often. You know these were you know these were big economic figures because of the way that they had helped market that just set that agenda of bringing the tax burden down privatising you know they were a big intellectual force and unfortunately in modern times the way that you know the time we all noticed the IA was when it not only endorsed Liz Truss's disastrous mini budget but also claimed credit for the sort of intellectual underpinnings and so I do think it's not to say you can't do it but I do think that you have inherited an institution which has got a lot of work to do to prove that it is intellectually robust rather than just a bit wacky. Well obviously I wasn't out the IA in 2022 I wasn't in Liz Truss's government I think I'm on record as saying I thought she was trying to do the right kind of things and went about it in the wrong way and a slightly ham-fisted kind of over-rappied way and I would still stand by that and you know whatever the IA said and did now I'm here now and it's three years later and unfortunately the problems the country has have only got worse since over those three years and the country really needs people to kind of step up and get involved in in the argument and that's what we intend to do here to answer the the earlier question you know of course we need to the next government which I hope will be of a free market persuasion needs to go about the necessary changes in a much more measured and sophisticated way and you know in particular it's important to keep spending and taxation broadly in line of course they're not broadly in line at the moment we're spending much more than we we bring in unfortunately what we really need and I've argued for this before is a you know probably a 10-year program for reducing the role of the state to back to the early Blair era's levels I would say bringing spending down bringing taxation down a bit each year beginning to roll back regulation every year getting beginning to reform some of the big problems we've got the health service universities planning we know about net zero it needs a serious program and that has to be developed now in opposition can't be done casually but the direction of travel must be set and it must have credibility behind it so that's what I would say about the you know what needs it's going forward so what does that look like though in terms of if you're because I appreciate your point you've you've you've got to put all these things in place but what does that look like if you're doing a budget like what would a budget look like for you and I don't mean all the minutiofe of you know fuel duty and things like that but just the how how can you get across a budget that brings in lower taxes lower spending or same spending whatever basically not increasing it what does it look like to you and how and how do you do it and just and maybe just so help with the framing you know you you as you say said that as a sort of framework you thought that trusses approach was appropriate it was just I think what you were saying is just to try to do far too much too fast so go back to her agenda and if if that agenda was going to work how would you have done it well I think I would have spent a lot more time explaining and and I think one of the problems is that because free markets and that are kind of freedom agenda has been so muted for the last 20 years and all all the political and economic problems have been framed around a state role the the the the value of free markets the gains they can bring to human welfare and prosperity are not widely understood and all that the kind of pedagogical work that the Thatcher and Major Governments did on this has been forgotten and has to be done again so you know ideally Liz would have been starting from a different point but I still think she should have done you know rather more kind of explaining of you know why she was doing what she was doing why it was necessary to stop and rise in tax spending but the unfunded tax cuts David were always going to be a market catastrophe well I I I I don't think this is the the moment to redebate you know whether this trusted the right or the wrong thing what I'm trying to do is is set out what I think we should be now doing and the problems Liz was facing the problems ratio was facing the problems the current government's facing are are the same problems the state is too big is doing too much we're running a massive deficit the the the tentacles of the government are in all kinds of economic activity and we need to to roll that back and that's the fundamental difficulty that we face and it will face whatever government comes in to answer staff your question I think I mean obviously it depends where we are by 2930 and things could be quite a lot worse than they are now I think in terms of the public finances who knows I think you have to I suppose what I would be saying is you need to develop you you need to prepare the ground you need to set out rather as you know both the Tories and Reform are beginning to some initial spending cuts that the show a commitment to to credibility ideally to be repeated year on year with taxation following it and of course you also need to roll back a lot of the regulations you know we need to get the supply side working again to to counter any fiscal squeeze that's going to be the difficulty so you know the the the whole sort of disastrous policy of of net zero the anti enterprise tax system you know ending the trying to get more for the money we spend on the NHS and so on all those things got to be done as well if we're going to get the real economy moving again so it's really really complicated task given the the mess that we've pushed the country into it is complicated I mean I noted that you have resigned your membership of the Tory party because you feel it's important the IA I mean what you said I think it's not too seen as to being too party political but is it also because you know broadly your expectation is that reform is most likely to form the next government and you want reform to give you a hearing I mean no is it the I don't think anybody really knows what's going to happen in politics on the right in the next few years you know anything could happen and there's a lot of things we just just can't predict you know what I would really like to see is that we get back to a situation that we had in the the 90s and you know perhaps the first half of the 2000s which is that every political party pretty well had to acknowledge that there was going to be a big role for markets and the private sector in keeping the country prosperous and because there was an argument about the scope but nobody was really doubting the kind of intellectual backing for that and that's no longer the case but exactly but can I ask you about that I mean do you think Nigel Farage does share your sort of economic libertarian views because I mean you know he is argued for nationalizations you know he you know he he is argued for the kind of welfare spending I think you would oppose do you do you do you think there's any chance that you can convert him to your way of thinking I mean I'm not here to defend him he said you know certain things and he said other things and I think to be fair to reform it is still developing as economic agenda I think that's the best one can say at the moment I mean this is exactly why I think organizations like the IAA but not only us everybody's got an interest in it you know needs to make the arguments about this so there is some political payoff for taking you know relatively strong free market positions that people you know enough people begin to understand as they did in the 70s that the old model the model of the last 20-25 years has reached its limits and something else needs to be tried and you know there's no reinventing the principles we know what the principles are that produce prosperity we just need to find a way to get back to them what are your thoughts then on things like the fact that you know we've had this announcement about the investment into connectivity in the north through this northern powerhouse rail and that involves spending I would argue as someone in you know in the regions in the north that connectivity is really important it does need investment do you agree and do you think that's about public investment or private investment or a mix of both and how do we improve the situation for the places that are struggling with productivity and with high levels of deprivation and everything else which is very connected to access to services access to infrastructure and jobs and good good good homes and things like that how do you marry that up with lower spending yeah I mean of course it's difficult to pick on one particular spending program and say are you in favor of this or not you know what happens look at the tone but not then the specifics of that one but more the the fact that in order to get the growth we need there are lots of places that need investment they need better businesses there and you know how you know when we need to invest more in those areas before you're going to get that the growth and the access to better jobs and everything else yeah I think my well my view is is is the relatively kind of boring one I suppose that you know if you if you get the business climate right private sector capital will come in and the business climate has been getting worse in the country generally over the last few years you know we do need to mobilize private capital there's a lot of it sort of sitting around at the moment and people are kind of reluctant to to invest it so that general question of improving the business climate is important I mean what I would like to see one of the the problems with the British economic model is is the basically it relies to a significant extent on you know very high productivity successful industries in London and the southeast and some of that money is then kind of recycled through the rest of the the economy through through various kinds of transfers and obviously that's a relatively weak model we want more private sector driven growth the costs across the country and to me the way of getting that would have be there's limits of fiscal space at the moment but over time to you know have something like the big sort of you know free trade zones that we're talking about at one point where taxes are lower in parts of Britain import cost to employment is lower business taxes is lower rather than lead to new investment doesn't that just move people move businesses from one area to another I mean that of course that's the the the counter arguments and there is a there is a risk of that but but I think you know the problem at the moment is that you've got the reverse effect that you know a lot of costs are the same whether you're in Manchester or Newcastle or London but the you know local skills and productivity are are lower so you know you need to find a way to kind of match that up and I think we've got that a bit out of line in our very centralized economy at the moment the these things go with risks you know the change in model is a risk and this is my personal view obviously but but we need to find a way of stimulating actual investment and real private sector activity in much of the country and at the moment that you know that's been a consistent problem in Britain since the war really David this law tomorrow we want to ask you uh net sea will be in one of them I know you've got a big problem with that we'll find out more about it after the break in a couple of minutes see you then hi I'm Stephen Carroll and I'm Caroline Hepke here to introduce you to a

hi everybody it is Dominic Sambrick here from the rest is history now you have probably been watching the scenes on the streets of Iran you may be wondering where all this comes from so on the rest is history we have just recorded a four-part series on recent Iranian history so it kicks off with the Iranian revolution that brought down the Shah Mahamed Reza Palavi in 1978 1979 and it's actually his son who is now leading opposition to the Ayatollas from exile in the United States so in this series we explore the history behind the Islamic revolution in Iran at the end of the 70s where did people at Ayatollah Khomeini come from where did their ideas come from why did they have so much support why was the Shah driven out of Iran in the first place and what did it have to do with American intervention and the British intervention in the 1950s and we look at the unfolding story of the revolution and then the amazing story of the seizure of the US embassy in Tehran the taking of initially 66 hostages by the Iranians this is probably the story that I most enjoyed researching and writing so please if you're interested in Iranian history and what's going on check it out and if you want to taste it we have a clip for you at the end of this episode another I would sort of argue presumably challenge for the IEA is how to continue to make the case for Brexit against a sort of political background where much of the debate is moving against and opinion polls show that majority of British people I mean either voted against it or now think it was a mistake every single economic analysis shows that we're somewhere between four and eight percent poorer as a result of Brexit if you can point me to a single economic analysis which shows we're richer I would be very very interested I mean so I suppose the two questions is what do you think has gone wrong with given that you were a great champion for leaving the European Union what do you think has sort of gone wrong with the execution of that and do you think it is possible to continue to make the case for Brexit? Absolutely it is and to answer your question about what's gone wrong is that we've paid the in my view very limited costs but we have not sought we're not yet beginning to reap any of the benefits because we haven't done any other reforms and changes that the people wanted to see and you know the polling shows that a lot of Brexit voters think the Brexit was kind of done badly and of course from my perspective I would kind of sympathise with with some of that but people voted for change and you know there hasn't really been much change yet in the way we run the British economy there has been some but it's been tentative and some of it has come from being outside things that EU has done rather than positive things that that we have done so that's my big picture I don't think the reports by the way that you you mentioned say what they say you know the famous 4% what you say the famous 4% OBR figure is a a figure for reduced productivity over 15 years they're not saying that's what's happened now indeed they're saying that what's happened so far is a cut of about 1.5% in productivity and growth as since the referendum now I might disagree with that I think the figure is a bit smaller I wouldn't disagree but where the economy is flatlining we can't afford any further blows to the economy well we should be the right answer to that is more reform and change and not doing you know some of the the the statist self-defeating policies that we are now doing so I have never denied and you found me on record quite often saying there is a small cost to leaving single marks in customs union I would say is under 1% I wouldn't quite agree with the the OBR on that or or America's I mean you know the NBR in America is an important you know collater and organizer of you know they are saying it's 8% so you know it's it's you know there are ranges of estimates around the place the collater it isn't a you know these are the views of a few economists and you know frankly I think it's a really bad piece of work that's that particular piece you know the doppelganger figures that it uses they are heavily weighted to the US they're 2/3 the US and if anybody thinks that if we'd stayed in the EU we would have been growing at the same speed as the US given all the damage that we've been inflicting on our economy since then they're living in a fantasy world I think there's a very very poor paper based on some very weak analysis and you know if I had say I will be closer to the OBR but putting aside kind of the the macro analysis of things if you talk to the people who voted to leave the EU you know a lot of them where I'm from they did it because they wanted their lives to be better they wanted to take control away from the EU so that there was more control over their lives and and to feel better off essentially if you ask them how they feel now I can guarantee everyone would say they don't feel better off so regardless of surveys of what the economic damage is in terms of you know personal feeling about how things are then they don't feel better off and also I don't think anyone would notice any change to their lives at all because of it other than it's just got worse so what would you say to them about why that is the case why now that they've we've left things haven't got better for them how would you explain it to people not talking macro figures and everything else but just what what in limb in terms why is it worse? Well I would say that our problems long predate Brexit and I think you know everybody knows that that you know a real underlying problem has probably come from the crash and the productivity weakness that's that's followed since then I think the answer you know the short answer as I said is that we haven't done the things that we should have done after Brexit. So what should we have done? What would you have done what would what should be different what should the changes have been? I stopped pursuing net zero for one thing and killing off our industries with super high energy costs that's something we should definitely have been doing and no longer had to do once we were trapped no longer trapped in the EU's climate legislation that's that's one thing I would say you know and this is where we get things that are unpopular perhaps but necessary significant planning reform building more houses in a way that we're we're just not yet doing I know that's straight off but but that's something absolutely has to be done health service productivity that's a big source of problems we we need to experiment now we need to look at a shift to in my view a shift to over a generational so a European style insurance system and get better value for money out of the the health service none of these things going to pay off straight away but we need to mark a different direction of course I think what people are really responding to to a very large extent is that the 20 year declining productivity the fact that GMP behead is now flat lining and you know let's be honest there's not as an ambiguous economic question they're responding to high levels of migration and significant change in a lot of areas that the people are seeing and didn't really expect to see can I just on climate change because obviously this is one of the things that you are most passionate about and the IEA this is obviously not a paper that you commissioned because you're really going to just arrive at the IEA just publish a report I easily could have commissioned there don't worry yeah but I but it's a report that says that the government's estimates of the cost of the transition to net zero are significantly understated I mean I suppose my two points about that report is one is actually there's there's no accounting in it for the actual costs of climate change but secondly it also takes no account of you know essentially protecting yourself from the volatility and and of course the externalities of being so reliant on fossil fuels so it seems to me even if you accept the calculations it is only half the picture well it's the report is not a major report on every single aspect of climate change and the response to it so that particular report is just trying to make the point that estimates for what we're going to have to spend over the next 20 or 30 years on net zero very massively they're all very significant and that the government's government has not generally been kind of upfront and clear about what is going to cost and that that is the point I think that particular report is trying to make and does it very effectively do you believe but you personally believe that climate change is real I believe that global temperatures are going up and that human activity is part of the reason for that I don't think many people would deny that I think there is very legitimate debate about how fast and what the impact is there's very legitimate debate about given everything we've done in this country already whether we are the right country to make further efforts given the lack of efforts that's being made in other places around the world and there has been no serious attempt to look at the costs of adaptation compared to the costs of investing in a new energy system and that is obviously the crux of the matter do you think we should stop bothering to try and because you you were saying there about how you know we have little impact compared to other countries who are not doing there but should we just bother not bother doing our bit then do you think we should just stop trying to make a difference to global temperatures rising well I think you know whatever we do makes almost no difference given the our emissions should we not bother I think we've done our bit it would be my view we've reduced emissions very significantly already and inflicted significant damage on the economy by doing so others need to now pick pick that up and we need to focus on maintaining some sort of industrial capacity and stopping people freezing to death in the winter because they can't afford to heed their homes we now see we're now on the verge of significant risks to the grid you know power cuts are a possibility in the next few years nobody has explained how we are going to deal with intermittency in renewables at satisfactory cost yet the rush on this subject to inflict further damage and push up costs is quite unconscionable in my view and it needs to pause and be much much better debated as an absolute minimum I mean my concern is just straightforwardly that I mean I am persuaded by the scientific evidence that warming over a certain level would be absolutely catastrophic particularly for the poorest parts of of the world and actually I think sort of leadership by countries like ours matter now I'm not remotely saying that every aspect of the government's approach to this is properly prepared, costed as efficient as as as you'd ought to be but you know I am deeply I mean I you know I am somebody says most of my time worrying about how we protect ourselves but the planet from absolutely catastrophic risks of which this is one and you know I really worry whether the debate is going because it seems to me there is we're heading into a world particularly with Trump in the White House where we are potentially heading you know we are increasing the risk of a genuine climate catastrophe, well I mean there's there's reasonable debate about that so I think my view you know I've looked at this quite a lot ever since I was ambassador in Denmark in the run up to the first Copenhagen climate conference it's not something I've come to recently I would say that view is is alarmist I think the actual figures don't bear out the most catastrophic predictions so far but in any case I come back to we've done our bit you know it's for China it's for India it's for the industrialising countries of the developing world to do their bit we have shown leadership the trouble is there doesn't seem to be a lot of followership yet and if we actually go and solve the global problem that needs to change. Can I just come back to the point you were talking about earlier about the reputation of the Institute because there's some there has been some criticism hasn't there about the fact that you don't declare who funds the Institute for Economic Affairs and the potential conflict that might be there when you're arguing for net zero at the same time as you know money possibly coming from oil companies and things like that do you think do you see a day where you're going to say be more transparent about who funds the organisation. Well I mean it's not so much our policy as charity law charity law does not require donors to make their identities public and we respect that I mean quite a few of our donors are happy to make their identities public and and you know we facilitate that as well. Do you actually ask your donors would you like your donation to be made public do you take. It's part of the discussion yes and that that happens but it's part of charity law we're not the only charity that doesn't declare all its donors and there's there's a mix of reasons why why they don't and you know for us you know it's a very real risk for donors that they're subject to you know potentially kinds of intimidation and I totally understand why they they might not want to. What is very clear is that you know you can't buy research from the research results from the IAA all our research is academic research is peer reviewed double blind peer reviewed you know it's reputable you can't buy a an outcome from giving money to the IAA that would destroy credibility overnight if that were the case so I'm comfortable with the policy and you know charity law allows that policy charity law is framed around that that policy and I talked earlier about the reputational problem in face because of being before your time associated with that disastrous trust mini budget the other thing which sort of strikes me though about what you might call the absolute glory days of the IAA is you get that to elected in 79 not long after that you get Ronald Reagan in the the White House and you know you get these two really important leaders sort of working together within this actually in this case market that you're very much the sort of intellectual leader in that partnership when it comes to economic reform one of things that's very striking to me is we now have a president in the White House who is telling banks what the appropriate interest rate for those who've got credit card debts should be he's bossing oil companies around and telling them to drill where they don't really want to drill and he's trying to take control of the independent central bank the federal reserve so you've got somebody in the White House who you know broadly has values that are the diametric opposite of the IAAs so the sort of climate for you is is not exactly the appropriate one is it well it's we're not in the same situation as the the 1980s though of course I mean it's a debating point slightly but of course we didn't have independent central banks in the 80s and 90s either at least in in Britain and you know it's possible to exaggerate the difference sometimes I'm not you know I'm not here to defend president Trump I feel uncomfortable you can't approve you can't approve with almost any element with economic policy can you do you I mean is there any element with economic policy you agree with well I'll say I'm not I'm not really kind of here to express the view I think you know we're a British think tank you know we're trying to provide ideas for the British political debates and all we can do is affect the country that we are in and the country that we you know our government governs and I really think it's best to kind of focus on what we can do to make ourselves more prosperous than kind of posturing around the world and telling other people they're they're getting it wrong all the time sometimes they are getting it wrong but it doesn't really help if you spend your time banging the table telling that especially when the British economic record is hardly stellar itself yeah but you earlier on you were all right slugging off their how they analysed our economy when we were talking about the review on how Brexit impacted our economics so you're all right that's it that's the kind of those are independent economists that's that's not the same thing I mean look I'm not in favour of tariff policies for example in general I don't think tariff policies are a good idea I'm not saying they should never be used in certain circumstances but I don't think they're they're great but you know we in Britain have to accommodate ourselves to a world where there probably are going to be tariff policies where there are going to be you know the kind of policies that Trump is pushing and all we can do in Britain is live in that world and make ourselves as successful as possible and that's really the agenda that you know that that stands on its own two feet and that's the agenda that I think we most usefully can spend our time pushing but if if you were to have you know let's just say you get in to the UK the kind of government shares your economic values your approach to economic stewardship and you would look at income tax and you were going to look at corporation tax and where would you want to see both the basic and the top rate of income tax and where would you want to see corporation tax and you've got let's say you got 10 years to to bring this about in your sort of ideal world what what would the tax rates for the UK be well I mean the rates should be lower the important thing is the burden and you know in the early Blair years we raised 30 percent of the taxation was 30 percent of GDP by large it's now 36 going to 38 so I want to get back to to 30 that's where we should be aiming to go a lot of people seem to think the early Blair years were quite a good time for this country why shouldn't we aspire so for you therefore it's the burden so Liz Truss was obsessed with the rate but for you it's just the mix of taxes you're not particularly focused on there's an optimal rate of income tax or there's an optimal rate of corporation tax I mean they should all be lower obviously there are you know some taxes are better than others economically and I would you know I would think we should be focusing on the taxes on transactions and capital first primarily but all the taxes need to go down and the kind of weird bits the sort of Manhattan skyline of rates that we've got in income tax with the withdrawals of this and that benefit and the personal allowance and so on all that really should be straightened out so I'd see that as as as bigger priorities is so damaging to to incentives yeah obviously you you know you've resigned to Tory whip and now at the i.e. do you think you're going to be more effective in that role than you you're wearing politics I suppose it depends how effective if you think I was in politics really you know we did get the country out you lost a lot of arguments David in politics you lost a lot of arguments we lost we won one big thing which was to get the country out of the EU which nobody ever thought we were ever going to be able to do nobody ever thought we're going to get a free trade agreement which we did so a lot of other things went wrong under that government but we still managed to achieve that you know there's lots to do here there's huge amount of opportunity you know I really feel that a lot of people in this country think things have gone wrong that we're you know whether we're running up against the buffers of how we do things and the needs to be big change and I'm sure the i.a. can capitalize on that and help develop a new agenda looking forward that's like you're knowingly we're out of time I hope you enjoy yourself in your new role it's I you know I just say got a lot you got a weight of history on you David yeah absolutely but it's a great place to be and there's lots and lots we can do so thanks for for your time and I'm sure we'll talk again there's no shortage of things to talk about yeah that's true thank you very much goodbye from me and goodbye for me bye bye hi there it's Dominic Sambrick again from the rest of history now I mentioned during the break that we have a new series on recent Iranian history so here is a short extra for you if you want to hear the whole series then search for revolution in Iran on the rest of history wherever you get your podcasts or search for us on youtube there are crowds in the streets every day there are attacks on banks and restaurants every day and already in some towns in Iran power has been taken from the legitimate authorities and it's been taken over by revolutionary strike committees now if you're with the revolution this is very exciting if you're not with the revolution it is terrifying and in his memoirs Ambassador William Sullivan describes standing at the US Embassy and looking out through an upstairs window and he sees in the distance troops holding back demonstrators he sees cars burning in the middle of the road you see smoke rising from burning buildings and he thinks something has to change we have to do something so on the 9th of November he sends a secret cable to Washington with the title thinking the unthinkable and he says the shower is finished it's over and if we don't act now Iran which is so vital to us will slip out of our hands forever he says we should ditch the shower right now and it may well be time to do a deal with the Ayatollah Ruhollah Khomeini if you enjoyed that clip then please search for the rest is history wherever you get your podcasts
