We should probably also redesign schools so that they need fewer teachers. For example, above certain age it is a waste of time if the teacher has to explain the same concepts over and over again to each class -- kids could instead watch a video, and then discuss it with the teacher.

Basically, the problem is that the current educational system doesn't scale well. It requires hundreds of thousands of teachers. Then people say "also, they should all be very smart, very empathic, well paid, etc." but good luck finding hundreds of thousands of people like that.

People understand why having a personal cook is expensive, so you either cook for yourself or you buy something mass-produced in a supermarket or you do a combination of both. Yet, we insist on everyone having a personal teacher. Not completely personal, but the ratio of teachers to students is something like 1:10, which is still too many teachers.

If we go even further, the school system has a dual purpose of cheap babysitting and education, but it is taboo to talk about the former, so we pretend that all teachers do it teach. If instead we admitted the dual purpose, we could have separate professions of babysitters and teachers, both operating at schools, but we would need fewer teachers, and the babysitters would not need to have university diplomas.
