In states with lower teacher pay, most teachers without a much-higher-paid spouse take summer jobs or teach summer school. Also, none of them get as much time off in the summer as the kids do. Plus, you can't pay your mortgage with vacation days.

Teachers often end up working weeks that are more than 40 hours, though with grading, lesson planning, tutoring, etc.

Given the (often ongoing) educational requirements, if you pro-rate it you still come out much below most positions with similar requirements. We absolutely under-pay teachers in virtually every public school.

My mother retired after working her entire career as a teacher, and I earned close to double her final salary my first year working in tech. She has her masters degree and I did not graduate college. And if you count the stocks I got at the end of that first year, it was over triple.

She was a special ed. teacher teaching emotionally disabled grade schoolers (including a first grader that tried to kill his grandmother with a tv power cord). There is no way that I worked harder than she did.

You sure they're not on 20 pay contracts? Everybody tells me "it must be so nice, getting summers off" and I'm like "actually I look for summer courses because I don't get paid."
