Even without COVID the public education system is such a travesty. When I was in highschool, one year, I had a math teacher who clearly didn't understand her own subject and would routinely get lost and contradict herself and was just generally useless in trying to teach what she did not know. In another year a math teacher may have known the subject but had zero control of the class and the students rebelled against him and there was never any real teaching because kids were acting out to an absurd degree. Basically, of my four years of high school math two were literally a complete waste. And that's pre-covid.<p>The obvious culprit, to me, is teacher's unions. Why don't we fire bad teachers and hire good ones? Seems like the teacher's unions prevent that. Compensating teachers based on tenure rather than performance is another teacher's union problem.<p>I find the whole thing very discouraging. Society is allowing immense waste of time, effort, and potential over very obvious problems.
