Earlier quoted context omitted.
I don't understand exactly what you're complaining about. Has anyone ignored the cost of closing schools? My impression has always been that everyone has known about the high cost, but, well, millions more dead isn't exactly a small cost either. I mean you may disagree with the choices which were made, but surely you have to recognize that it's a bit more complicated than what you're suggesting?
Yes, people have stated that 'the kids will be fine' quite consistently. Also, all costs other than deaths have been underplayed by people in favour of lockdowns. Memory-holing this is literally insane (where insane = disconnected from reality). That's not to say that what was done wasn't the best of a suite of bad options. But I saw nothing but fairly extreme downplaying of the consequences of lockdowns from people…
it's a trade-off, I think we did what we had to do.
