I think the argument that controlling covid is good for the economy needs real examination.
The argument has some merit if you are talking about NZ / Australia and then you get into a whole debate about whether that is plausible here and what the exit plan is etc.. But if you are talking about European countries most of which have been in and out of lockdowns for over a year and where there has been a devastating economic impact and huge level of government spending, I don't think it really holds.
I agree that if the population is afraid of catching covid this will damage consumer confidence and have an economic impact. Reduced consumer confidence always damages markets.
But that has to be compared against what has actually happened which is most businesses which consumers would use being shutdown and / or operating at such a limited capacity that they aren't profitable for 16 months.
If you run a pub and covid rates are high, maybe fewer people will come to it. If you run a pub and it has been shutdown by law, no one will come. Same for hotels, leisure businesses, beauty services, to a slightly lesser extent retail etc, even dentists in the first lockdown. I don't see that the profits of these businesses could possibly have been lower if there had been less lockdown.
And it is not like the constant cycle of lockdowns or restrictions in between times have kept cases consistently low anyway so as to give people the confidence to go out and spend. In periods where cases have been low businesses have mostly been closed anyway. In periods where we have partially opened up, cases have gone up quickly. So "controlling the virus" has led to very few periods where cases are low enough for people who are worried about covid to feel confident. The UK isn't alone in that - the same pattern has occurred across Europe so it can't just be blamed on our government.
In terms of people being ill having an economic impact, of course it will, but again this ignores the extent to which this has happened anyway and overestimates how ill the majority of people get with covid. Around 30% of the population have had covid. For most it is a mild and short illness or has no symptoms at all (particularly for the group most likely to be out at the businesses which have been closed). We can see now that self-isolation of contacts is a much bigger issue than actual illness - logically it has to be because most people with covid have more than one close contact. On that basis, self-isolation of close contacts is a more damaging economic policy than more people getting covid.
There is also the issue of the very high level of government spending needed to support lockdowns. We are starting to see signs that this is causing inflation. If we had borrowed this amount and spent it on almost anything else we could almost certainly have saved or improved more lives.
The question of what would have happened economically if we hadn't locked down or had done much less of it is really complicated (even for top economists) and I don't think anyone should be calling people on the other side of the argument stupid. I think there are plenty of valid and interesting arguments to be had about it.
I do think that people intuitively understand more about health than economics though (unsurprisingly given the education system and what is in the media etc) and that once numbers get into billions or trillions people can't always process them or understand the impact. I have seen it argued on here that businesses selling masks could counteract the loss the the economy caused by hospitality being closed and that adding 1% to income tax for higher rate tax payers would pay for covid.
I also think the health impact of recessions is ignored and debates about lives saved end up being about covid vs suicides (where suicide numbers are small in absolute terms though obviously devastating when they occur). Recessions and particularly unemployment provably shorten peoples lives (with most impact on the poor) due to a complex network of factors like nutrition, housing, access to healthcare, addiction, poor mental health, needing to work longer hours or until an older age in physical jobs etc). My opinion has always been that over time the lives lost as a result of those factors will outweigh lives that would have been lost to covid (particularly in a time where the government will have less to spend on mitigating them because they spent it all on locking everyone in their houses).
I don't really understand the view that the current conservatives are neoliberal or anti-lockdown. They have kept the country in lockdown or something approaching it for around 15 months, including going much further than other countries in banning contact between families and are now talking about vaccine passports (probably the least liberal policy you could conceive of). There was a study which found that the UK's lockdown has been the 5th harshest in the world. The view that we have had a light lockdown is not backed by the evidence.
I consider myself a liberal and am generally anti-lockdown. I use liberal in the traditional sense that I am pro individual rights, civil liberties, democracy, free trade and freedom of speech etc - I'd characterise it as "live and let live" . I am also generally pro welfare state, which now tends to go alongside liberalism. I find that no political party really represents my views.
