Why are there hardly any good teachers?

you say they can't control them.. thats because they don't have any rights any more, students can treat them like trash, they can ault them they can do whatever they like and get away with it and the worst thing is they know they can get away with it, and the teachers can't do jack. that's why i'm glad i'm not a teacher coz i would want to knock most of them to the ground and keep punching until i was hitting concrete. you can't blame their apathy, it is a shame tho that there are still people out there who want to learn and aren't getting the help they need.
