OP it's probably really natural to feel like this in such unusual times, but I genuinely don't think there's anything sinister going on (beyond perhaps some of those with the money to buy millions of shares, opportunistically trying to make some money out of it all, which they do all the time anyway)
Some people at the top are properly sociopathic, but it's hard enough working together with nice, team-spirited people. It just doesn't seem likely that they could get together to do anything properly global - there would have to be so many thousands of people in the know and they'd end up falling out anyway.
I think this is pure incompetence and also inexperience with a pandemic. In this country, a core bunch of very privileged people have got into power, ousting anyone more moderate, purely on the basis that they promised to deliver Brexit, whatever. So they've been focusing on that, and just do not seem to have the imagination or empathy to realise the effect of this pandemic and lockdown on ordinary people - or possibly to care all that much.
On top of that, the government has been cutting away all the infrastructure from under us because of austerity. When things are okay, things were only just holding together, but anyone not in direct need of services wasn't necessarily aware. A pandemic has revealed what massive gaps there are in NHS staffing and social care, and that's made the inexperienced and lazy inner cabinet start to panic.
Look at New Zealand and how their government is handling things, and it looks so, so much better. We just need a bit of caring and thoughtful leadership.
