I understand, but there is already a crap ton of evidence that our covid school policy has done some major damage and the spike in mental health problems among kids is also pretty well established. That is my wide lens view - derailing a year-plus of school at every level and masking young kids (going on 2+ years in some places) is going to have long term impacts across the larger population. Kids are resilient but they aren't immune to these impacts (which may not even present themselves until you start cognitive testing, etc)
My narrow-lens view (my own kids) is taking that knowledge and trying to make up for it as best I can but I'm fortunately in a position where I have some resources to throw at the problem.
