SWBKCD, I think your response is unjustified. The vulnerable groups like all groups need to take responsibility for themselves. We cannot protect a minority by actively destroying the livelihoods and lives of millions who are at little risk. Without a functioning economy we will not be able to provide the resources to tackle this crisis. I would worry more about the associated social and economic costs of a depression than a virus which evidently is mild for the vast majority.
Put Covid measures in place, let people make their choices and get back to work.
