It also ignores the 12% that will wind up in hospital, so 39.6M with thousands of dollars of hospital bills. Avg was $37K, last time I checked, or so it was said. It also ignores the 1 in 4 who end up with long haul Covid. So, at this point, an estimated 43% of the population have had Covid so that's another 39M with long haul Covid that may or may not be permanent.
Since Covid is endemic now and there's no way out but through, eventually we will all get Covid. As you said, 3.3M will die, 39.6M will end up with crippling hospital bills they will struggle to recover from financially, and 82.5M will end up with long term illness or disability. Possibly permanent.
If it ends up being permanent, that 82.5M statistic puts us right up there with bubonic plague as far as the economic fallout goes because it roughly matches the loss of economic output or potential. In another sense, Covid may even be worse because at least with bubonic plague the populace died so their continued care wasn't a further burden on the survivors like a large disabled population will be.
That's a harsh way to put it and I don't mean to sound callous, hopefully you'll take my meaning. We're in for a world of hurt. And it's too late to stop that now. We had our chance and we blew it. No way out but through.
