Problem is we were in new territory, if things had gone a different way and a deadly variant had emerged the outcome would have been catastrophic and as has been seen you just can't rely on people to do the right thing of their own volition.
Without the measures put in place and furlough my dad would almost certainly be dead by now if he'd have got COVID before the vaccines and there was no realistic way it would have worked just shielding the most vulnerable as per recent comments the actions of my sister would have made that difficult and in general there are far too many multi-generational households for it to work.
What I'm critical over and over again is how slow and seeming little interest there was in actually understanding the disease so as to better approach it without having to resort to lockdowns, sure these things take time, but for instance it is only thanks to a small number of doctors, who'll never get the recognition they deserve, from Italy and the UK who took it on themselves to collaborate on understanding how to treat the disease best that our medical knowledge came on in leaps and bounds reducing the death toll by around 75% while a deadlier variant was still in play and before vaccines. Related to that and an error I also made is of seeing COVID as having a roughly even impact on the population as a whole, while it seems there are some, not just down to age or poor health, who are highly susceptible to it compared to average and once the disease has worked through them things ease off quite a bit - vaccines and Omicron have played their part but IMO that is a significant factor in why things have have come down a long way from the peak and while a very clumsy way to do it measures put in place have succeeded in flattening the curve of that.
