It always surprises that left-leaning politicians and media were the most fervent advocates of school closures, because it has disproportionately affected kids from the poorest backgrounds. What I see around me is that educated couples invested the time to make up for the lack of school education (and were typically home working themselves), so those kids will probably do OK, other kids were left on their own all day.

I think it is more of a relative problem than an absolute problem.
