@Fido,
I don't agree with cash prizes for achievement (though I don't dismiss it out of hand, either -- read a lot about it a few years ago, it's interesting), but yes, I agree re: pay and prestige (that's what I was saying earlier). (And Obama seems to agree too!)
The pay/prestige part is both because of the message (education is important, teaching is important) and also the practicalities of getting the best people into the classroom. I know far too many people who would've been great teachers, but who had a variety of options open to them and after they got their teaching degree, ended up going into a field that paid 2-3 times as much. And sometimes it wasn't even the pay, which is why I keep saying "prestige" -- it sometimes was a matter of just having a nice finite respected job.
Teachers are often presumed to be not that bright -- "If you can't do, teach." It's often considered something that people settle for if they couldn't get a better job. Or something that pretty girls do until they find a husband and have their own kids. And the job itself is full of the kind of ongoing negative feedback that usually only people in sales have to deal with.
Now from a parent perspective, that's just kind of too bad. I'm gonna advocate for my kid, and I think boomer for example should (as she is) advocate for hers.
The point is though that from a gifted teacher perspective, it's often enough, cumulatively, to say whoa, I'm doing something else.
And we need those gifted teachers.
