We're not "getting through the situation". The more spread the higher the likelyhood of new variants appearing, the more people that die of completely unrelated causes due to there being no available hospital care, and the greater the economic chaos.
It is a dramatically higher cost that gets paid in loss of life for those who choose not to be vaccinated and those who can't, and in staff shortages and basic infrastructure weakness for everybody else.
We are, just not in the way you'd prefer. Plagues much worse than this one happen regularly, and humanity gets through it.
> It is a dramatically higher cost
A dramatically higher cost than what we're currently doing to our youth? That's an opinion. So some teachers die, and the profession becomes temporarily younger and more male than before due to self-selected risk profiles. Sounds like how any "dangerous" job already works. This doesn't constitute a crisis worth sequestering our children, to me.
In one sentence you literally admit that plagues much worse come with a human cost of life that it just astounding, and then on the next sentence you complain about children having to lose a couple months of class? Are you dense??
"It is what it is" but as of now staff can't work because they're out sick.
