I've been very surprised by the lack of vigorous left-wing opposition to lockdown. I'm a left-of-centre floating Labour/Lib Den/ Green voter. I agree with many of the arguments about the long-term economy but it's the immediate impact of lockdown on the poor, vulnerable, and those ill with diseases other than covid that terrifies me. I also find the nation-state-monocular-vision aspect of lockdown policies depressing, because I don't understand why I should care more about an 80 year old in a care home in Northumberland than a hungry 10 year old in Africa. I don't know either of those people. I feel human sympathy for both, but I don't have more sympathy for someone because they're British.
A friend told me that in Nigeria (where she was born, and all her family live) Covid-19 is seen as a disease of the rich, a sort of decadent health problem like obesity and gout!
You could imagine a 2x2 matrix plotting benefit from lockdown (high or low) against cost of lockdown (high or low). There are a lot of people in the high benefit / low cost box (those Tory pensioners in their lovely houses on their big pensions) and a huge number in the low benefit/ high cost box (almost all healthy people under 40). I think this tends to ossify political debate, because those with something to gain have little appreciation of the sacrifices involved, and those making sacrifices have so little personally to gain. But because about half of the people in the low gain/ high cost box don't have the vote, and v few of the others have an influential voice in public debate, I think this group is not being well represented. Look at the cabinet/ constituency of SAGE. They're almost all much older than the median age, as well as being richer and more privileged.
I would put myself in the low gain/low cost box, because I'm young enough not to be worried about the illness (and already have antibodies) but old enough to have a fairly small mortgage and a very stable income. But my children are in the low gain/ high cost box, as are my students, so I sympathise with that position. I know only one person (very vulnerable teacher) in the high gain/ high cost box and perhaps this is the smallest?
