Hell no, teachers aren't paid well,
but let me open another can of worms here, speaking from personal experience here.
how Good/Bad are teachers at teaching kids STEM subjects?
can they pass the exact exams they make the kids write, Sure some of them can,
but others? ummm I'm guessing no...
so again, for some its a job, and an average paying one, similar to a Data capture or something entry level.
while others see teaching as a calling and take genuine interest and show passion for it,
so again it depends on the individual and school I guess, and I thing that's how they should be paid,
as private school X can afford to hire the best and pay the best, while Township school Y can pay only Y.
