That's an understatement. The teachers spend more time with disruptive students than teaching. Why does this go on? I suspect the Dems really just don't give a crap.
It goes on because white liberal teachers feel sorry for”those poor black children”and are sometimes even afraid of them.
On top of that,teachers are so fearful of lawsuits that effective discipline is limited.Back in my day,a few whacks from a paddle was totally acceptable.Nowadays the kid would want to fight you and the parent will want to sue you.
