Reminds me of a teacher my dad told me about when he was in trade school (he went to a trade school for high school back in the 70s/80s). He said all the students called the guy Mr. Hitler behind his back.

He would regularly make fun of students, call them stupid for not understanding things, send kids to the principal for the slightest infractions, etc. My dad didn't grow up with money but started working at like 14, and he said it always bothered him the most that Mr. Hitler would especially pick on poor kids.

"Oh, is that all your family could afford for you, rags and old shoes?" "Really, the same pants two days in a row, what, your family can't afford to wash them?" Just shit like that, in front of the whole class, absolutely demeaning and stuff that wouldn't be tolerated today.

Well, apparently Mr. Hitler suffered a stroke at some point during my dad's high school days, and according to him, not a single student gave a damn to do anything to help him. He had trouble walking/was in a wheelchair, kids would let the door slam behind them despite him trying to get through. If he had several things to carry, students would ignore him requesting help to carry them, pretending like they couldn't hear him.
