Re the current supply mess from the simplest of PPE through ventilators and on to entire hospitals.
I think that after this the UK should ensure that as much of this as possible is done in the UK with spare capacity built in. Several new BIG SOTA hospitals should be built and all including existing facilities should be stuffed with every kind of machine, aid and ppe. Production capacity should exist in the UK to supply all our needs and including a ramp up ability in times of national or global emergency as if there's a global event we can't just go out and buy this stuff as every other country will be trying to do exactly the same thing.
Doing all this would be a massive strain on the economy but the voting public don't seem to mind the sky rocketing national debt so so be it. I think this could also be an opportunity to more radically change the way the UK's economy functions.
I can't see this happening, but it's what I'd do
