I know of some teachers in the area that can't afford to buy a house.
The father of one of my son's friends is a teacher. They live in low-income housing. They have 3 kids, and live in a tiny apartment.
I think that a reasonable pay for a teacher depends on the area they live in, and I think that a teacher should be able to buy a modest house.
I believe there are other careers that should be paid more, but I also think that teaching is a respectable job and they should not live in low-income apartments.
I can relate firsthand to that. I found out that I couldn't get a loan on my salary alone. I think with the formulas that I could afford to buy an overpriced bathroom or something. We do have a decent (average) home, but it's because of both of our salaries.
I do think that a lot of teachers do live comfortably and not in low-income apartments. That being said, I don't see really any here that are rich unless their SPOUSE has a lucrative job.
A reasonable teachers' pay depends on a lot of factors. I will conceed that some are overpaid and some are not. It is an important job as well as other jobs are too.
