Perhaps these are underlying reasons, but the fact is that >90% of kids want to behave. And that >90% of parents want their kids to behave. But teachers just aren't on the side of parents. Reactions of teachers to my kids were always somewhere between disappointing and infuriating.

Also, as a rule, teachers do not know their subject matter these days. Whilst I do remember their knowledge being less than perfect in the past, it was not like this. I understand teacher pay is a factor, but I refuse to believe these people have even the capability of educating kids.

Luckily good teaching materials are more accessible than ever as well, it's just ... all of them are outside of school.
