Teachers should never have been disciplinarians. Their role is to teach kids. If kids are a behavior problem, the teacher should be allowed to expel/ban them from the classroom. This is the only thing that school administration needs to back teachers on. Education being compulsory for students who don’t want it is an extreme social mistake and one we should remedy as soon as possible. These disruptive students do far more damage to other good students than the benefit they provide if you “try hard” to make them work anyway. Not worth it.
The status quo in America gives teachers far too much power to decide the lifetime earning potential and fate of young students. Teachers are extremely tyrannical and that fact is never brought up at all in education discourse. (not even by the “anti teacher” right wingers)
