I mean, sure, I had a few bad teachers myself at certain ages, but there were good ones too.

Making it up to be some kind of power-trip seems wrong to me, although there certainly are a few of those.

I will say though, that teaching the same curriculum year in year out grinds down almost anyone.

I felt lucky that each student was truly different since their various issues needed such radically different approaches, but that was spec. ed., not normal school.
