When I was in high school a significant number of the teachers left because they couldn't deal with it...
...the ones who put in the extra hours, and who worked the hardest, were also the ones that some of the parents decided were most available to be (literally) yelled at about their kids' crappy work attitude. The ones who did the bare minimum and obviously didn't give a shit faded into the background.

Kudos to you for being one of the greats, sorry you have to put up with the dross. :(
