Your comment about "it must be nice going to work every day not having to worry about competition or producing results" is a semi truck load of baloney. Teachers are constantly being harassed for their grade stats and whether their lessons are in line with the teaching methodology currently in vogue. There is currently no room for teachers who want to be mavericks and teach the way they think they should teach, to "make a difference". Such teachers have a special name: unemployed. Your whole discussion is about some alternate universe, not in line with current Earth reality in large cities.
Teachers are not allowed to “teach”. They are only facilitators to promote a socialist “group (non) think” worldview (curricula) designed by evil, satanic Billy Ayers-types. That is why the great (real) teachers always quit.
Teachers don't have to worry about competition and they have little worry about losing their jobs -- unless you also also deny the reality of rubber rooms. Yeah, they have to put up with a lot of crap from their supervisors. So what? Trying to compare what teachers have to deal with (big city, suburbs or rural) to what the private sector has to deal with every day of the week, and weekends, is comical.
My universe is much more common than yours so thank you for marginalizing what a large percentage of parents/taxpayers have to deal with. Your reality is the only reality so please don't let any other circumstances influence your world view in any way.
Perhaps teachers who don't like the system should find more meaningful employment in the private sector? One of the best lines ever came from he first Ghostbusters movie when the professors were about to be fired...."Personally, I liked the university. They gave us money and facilities; we didn't have to produce anything. You've never been out of college. I've worked in the private sector. [states fearfully] They expect results."
If you truly have any interest in current Earth realities" that quote provides it.
