That's a straw man.
That pay range is roughly what teachers get in former-USSR/Warsaw Pact eastern Europe, and in those countries it's a comfortable income.
Also, going back to what they did a few years ago isn't "more work". May actually be less, given how often people look at AI output, roll their eyes, and say "ugh, slop".
Also also, questions of pay are obviously after society decides what it wants the role of a teacher to be and finds out how much it needs to spend to hire enough people who will do whatever that job turns out to be.
