This one was super weird, I was in highschool when they introduced it.Refusal to discipline troublemakers in an effective manner. I know places where kids more or less openly deal drugs and no one gives a damn.
Even societies with well paid and educated teachers have crippling problems.All of it.
Teachers get little to no pay, the half that actually want to teach can't discipline the kids or go outside of what the school allows in teaching so it all stays in one strict regiment of tests and textbooks. The other teachers couldn't care less about their jobs and don't want to help students who show any real interest in learning.
Students are rabid juveniles who have just as feral of parents who will try suing a school if a teacher so much as tells the little shits 'no' so classrooms become more of a jailhouse having to deal with kids until their parents begrudgingly take them back home.
Most subjects in school are completely pointless or have no standards. English, vocab, and math were given easy passes if the school didn't want to have people breathe down their neck because some ghetto kid was too busy skipping classes and threatening classmates and would have to be held back another year.
And then of course it comes to money, which they never seem to have any of.
And then after all that you get to go to a university where you relive your years in preschool where everything is soft and colorful and no bad feelings are allowed.
