It's possible that the number of coronavirus deaths will be higher than the number of UK military deaths in WW2 (not so in China, Germany, Japan or the Soviet Union, who had millions of military deaths, or Poland, where civilian deaths (mainly Jews) were in millions).
The big difference between WW2 and this pandemic is that the population is more in control. We can all slow it down, if we follow the official guidelines. We don't have an external political enemy, but should all be working together globally to defeat it.
I don't think it will be over for at least 18 months and I suspect life will change in ways we can't quite imagine. For a start, I think people will have become used to working remotely and might embrace that way of working, which would incidentally, be better for the environment.
I suspect some jobs will have disappeared forever. People will question whether some of them are really needed and people will gradually drift towards other occupations.
All countries are going to be massively in debt. The flipside of that is private wealth (public debt = private wealth) and any future government will need to decide how to manage that. It could be the world's "Zero Hour", when we reset our priorities.
