Our school district (in the USA) used much the same method as you describe for Japan: alternating days, 50% capacity, etc. Then the State Borad of Education mandated all schools closed. In our community, most of the parents in town are able to work from home. But its a very strange place, and I would expect worse outcomes most other places. Even so, serious psychiatric illness is tearing the kids up. The child clinical psychologists and the one remaining psychiatrist in town are double-booked, at least. It's been its own shade of awful. I don't think that there could have been a better response from the schools here. It's been very difficult to plan for anything more than six weeks out, and the kids who have returned to school have needed more care. And who is caring for the teachers? I don't know what the dropout rate would be for high schoolers, but many of these kids are just gone. Across all economic levels (the delicate proxy that we use, money lumped in with social status or prevalent parents' level of education and stuff).
