Those are actually the least solvable problems. A disproportionate amount of poor people are going to lose their jobs during the next 3-6 months because of a recession. A lot of people especially in the US are going to suffer because of the vast income inequality that has arisen. So there is no good solution, just like quarantine isn't a good solution but at some point we have to do it.
I understand that. In which case at least they should make school optional.
Several Universities are closed, several schools are closed and we need to worry more about the spread because if we don't we'll have the problems you mentioned in addition to a massive spread.
Who is supposed to watch these kids if the parents can't stay home with them?
What about the thousands of low income kids that rely on school for most of their meals?
I'm sure these are solvable problems, but I think there are good reasons that it's taking longer than most people want.
