If we want schools to stay open ft, we actually have to accept measures that would help achieve this
This is more difficult than it seems. The question is, how safe is safe enough to have them open?
There isn't really an answer to that question. Some people like the "do as much as you can whatever the consequences" an "one death is too many"idea, but it doesn't acknowledge that there are always trade offs, and there is always a calculation. Pretending their isn't just mean you don't acknowledge what that is.
Having kids back ft is an acknowledgement that we've, on purpose, set up a society where that's necessary. Parents need to work, and they need a place for their kids to be. Even forgetting education, people need the childcare. We could choose to return to a society where a lot more families have a parent at home, and actually I suspect a lot of adults might like that, but I don't see the political class going for that.
There is also, always, the question of what can we do, and what will work. Places asking 5 year olds to mask all day, I suspect won't be able to keep it up. Even with many older kids, it's unclear if masking will work they way people assume to prevent spread in a school environment. It's one thing to say that in a grocery store or even an adult office, masks will prevent spread. In a school, or certain other work environments, it may not help much at all.
