There may be opportunities for more blue-collar variants. I'm trying to think where but there was some program to hire former soldiers as teachers, which is a bit like that.
If we 3X the minimum teacher pay, we'd attract a whole new class of highly effective teachers.
That would solve the aforementioned issue, because people will move to BFE for the money.
Specialized and advanced subjects can be taught easier and cheaper. Their students are capable of learning virtually, giving them access to the best teachers in a subject area, and at as fast a speed as they can go.
What Public schools need to focus on are the lowest common denominators, your arithmetic to liberal arts, so that students are prepared for a more-self-guided education in specialized/advanced subjects. I'd argue people with experience in industry wouldn't even be valuable at this level, as their experience no longer generally prepares the students for further education.

That would be the Prussians, the origin of the compulsory universal education system with obedience and conformity as its foundation. The indoctrination worked very well, no wonder the system consequently spread all over the world.
