I am surprised you weren’t more aware of the environment during your student-teacher practicum — I knew quite a few when I was at university who learned after the first one that they needed to change direction. Go with a job that will allow you to pick your own clients.
I don’t see things getting much better in public education without a change in parenting — which means we have to raise and educate better parents. A lot of kids become future prison inmates (the most common denominator among inmates being level of education) because their parents were self absorbed or anti-intellectual or both.
Teachers are not the hinge. Parents are. You can only work with what walks in the door. Parents produce what walks in the door.
