It can't possibly be any worse. Even good teachers have the impossible task of teaching multiple kids who all understand and learn differently to move at the same pace for years and years as they erode through the system. Combine this with children's anti-social behavior, parent politics, office politics, district politics, state politics, national politics, and a univerdal egalitarian neuroticism around education the teacher must navigate.
Likely since we are about number 35 in the world despite spending more on ed than any other nation this can't be any worse.

I love homeschooling my kids, so I definitely like teaching, but I would hate working in the school system. I'd also probably do something that would get me fired because I will do what is right, not what they would expect of me.
