but, so what?
see, the problem here isn't that they opened the schools, it's that they provided terrible expectations when doing so. the science underlying opening the schools was always that the virus has almost no effect on healthy children. nobody ever seriously argued that your kids weren't at high risk for exposure, they just consistently and carefully pointed out that it doesn't fucking matter if they are.
but, the government - in an attempt to calm people's nerves - sent out a lot of bad information, insisted it was "safe" and that people shouldn't worry about it. stay calm and keep shopping.
this has led to haphazard behaviour, such as people letting their kids interact with older people. but, the problem here is that people were led to believe that this is ok - not that the schools were kept open.
if people were told the truth - which is that schools are a high-spread environment and your kids are likely to get it within a few months, at least, if they go to school every day - then perhaps they would have taken proper precautions.
so, yes - people are right to be concerned about schools, but only in the sense of ensuring that kids are kept away from the vulnerable, for a while. the social decision that was made is that it's more important to send healthy kids to school than it is to worry about the health of the very vulnerable. but, that was not communicated, and the problem here lies at the foot of the state for bad messaging around that, in telling people it was safe, instead.
we can still adjust.
keep your kids away from your parents. it's a few months. it's not that terrible.
