FWIW, here are (according to NEA) average teacher starting salaries by state:

The data is a bit old and I'm assuming things haven't drastically changed since 2017-18.
A lot start in the low- to mid-$30s per year, which depending on debt burden (hence my response to Lemon Ears), isn't enough to live. When you factor in unpaid hours of work outside the classroom, it's really hard to have a second source of income let alone raise a family. Especially if one lives in a high tax state and/or high COL area.
Teachers only care about money. Why do their students have no skills?
