> This framing assumes that the teaches had an accurate risk assessment, and the parents didn’t, but in retrospect we have seen that depriving kids of socialization was much more damaging to the kids than covid exposure was.
A few thoughts in response to that:
1. This is not the assessment of my friend at all. His kindergarden, btw. remained open during the whole pandemic and the parents that made him question his life choices were the once who sent their kids despite clear symptoms. So the children that have been deprived of socialization we are talking about here, are the ones who were ill. Something that happened to literally every generation there ever was.
2. In that moment the risks that were weighed against each other weren't just about the kids. Kids were one of the biggest contributers to the reproductive factor of the virus. So the choice was between moderating that R-factor so it is smaller than 1.0 and have the infection numbers go down or having it above 1.0 and risk saturating the health system (which can only handle so many infected people at once), which would also risk the lives of totally unrelated people who never got infected with Covid at all, but had chronic illnesses or accidents.
So on a level of "humanity VS virus" it was pretty clear that A) reducing the R rate till effective vaccines got distributed is a good strategy and that B) we had to ensure a good balance with the side effects of said reduction measures. At least where I live children have been the hottest discussed topic and every measure that affected them was very carefully (some would even say: too carefully) chosen.
Now we could do the math and calculate how many human lives that would translate too and then pose the question whether the "business as usual for kids" is truly the ethical right choice, given it clearly pumped up up the R factor and all that. On the one track you potentially have kids with psychological problems (back then this was just a guess) and on the other side with near mathematical certainty a pile of corpses, which are all older.
Now this is a hard ethical question and all depends on just how badly you predict those kids are affected, and how high that pile of corpses is going to be — but let's not forget there is always the benefit of hindsight.
Back then it was quite clear what had to be done to beat that virus. The matter of discussion was just whether individuals and organisations were willing and able to do it. Many were able, but not willing.
