I thought so at one age but then I tried a lot of different schools
The last school I went to as a kid was of the "Sudbury" model where there's no schedule, kids organize their own classes and stuff
I was still ostracized and abused for being too smart and telling the truth too much
Teachers should have handled things more fairly but that was in the teenage years, at some point the kids are responsible for how we treat each other ourselves
If corruption starts in childhood from within the children, and good people are outnumbered by corrupt people pumping out more babies, what can a teacher or their chosen system do?
Again, I assume your kids aren't part of the problem, that's not sarcasm
