There is a better way: Allow schools to offer only virtual classes this fall, and convert schools and other large unused spaces into Safe Centers for Online Learning. We could call them not schools, but “SCOLs.”
This is not a radical concept. Many universities are bringing some portion of their student body back to campus, but still holding classes mostly or exclusively online.
I don’t know if this is the best solution, but it sure seems better than the terrible plans I’m seeing in my area right now.
