There don't seem to be any easy answers about the schools. If states had taken this seriously during the spring we'd be like other countries who are getting back to normal including schools, but instead we're looking at the biggest still ongoing first wave of any developed country, with no sign of it abating.
I just heard a horrifying statistic on Pod Save America. 40% of the LA Unified School District kids never logged on to the remote learning even once. That does not bode well for the future of kids who either don't have the equipment and internet access at home, and/or don't have parents that can keep them focused and make sure they are doing it. When this if finally all over they will be left further behind than they likely already were. On the other hand having schools open seems likely to have a high likelihood of turning many of them into super-spreader locations that will make where we are now with covid seem completely in control by comparison.
