Depends on where they live and when. In some areas, quite frankly, state dollars cannot in any way compete with private dollars. In some of those areas teachers wouldn't make enough to acquire a run down apartment, let alone anything resembling a middle class lifestyle. This runs across the board with government employees, and thus there is a dearth of bureaucrats *everywhere* with that economic reality.
For many teachers, I'm sorry, but they make a comfortable wage, pretty good benefits, retire earlier, and many of the folks that work in similar fields make far less and work just as much (if not more).
Then compare the wages of a starting public school teacher against that of the adjunct professor at a university, and you'd probably get laughed at if you argued that the public school teacher had it bad. You'd practically come out ahead if you gave up the idea of acquiring a PhD and teach at the postsecondary level in order to teach kids at a public school.
Every late summer, we have to indulge a certain segment of the professional class's martyrdom complex, while plenty of "unsung heroes" remain in the shadows (but do not demand nearly as much public pomp and circumstance).
It's not a popular point to bring up with teachers that the quality of oppression has been mixed if not overstated, but it's the truth.
