The other thing that doesn’t make sense to me is the economics of it. The pay for the staff is very low but the cost of service to parents is very high. That means so much of the cost is overhead which would make the whole thing quite unsustainable, even when ostensibly covered by the government.
I live in Canada and a similar issue is occurring with our universal health care system. The costs are skyrocketing even as wait times are increasing.
Yay teacher's union?
Really school funding and public education in the US in general is in a very strange place across the board and has been for decades
The results for a given teacher are poor no matter what the reasons, it's a bad "hey get a union" rallying cry IMO.
