jfruser,
Can I ask what your point is? My geography degree is also useless outside the GIS market. A business degree isn't much use at an engineering firm. Are you saying that teachers should be paid less or just that bad teachers should be fired?
Of course none of this has anything to do with the OP.
An education degree or cert is a "barrier to entry" credential, not a degree that has much use outside the education bureaucracy. A geography degree may be limiting, but it is assumed that there is a useful body of knowledge and skill transfer for successful graduates.
Contrast this (ed degree) with, say, a degree in mathematics, which is much more flexible and opens up other doors: tech firms, aerospace/defense, computer science (especially in the old days, when CS was taught from math depts), etc. IOW, the market acknowledges that a math degree has a much greater value than an ed degree.
I think it is safe to aggregate public school teachers under the same umbrella as gov't employees when I write that I think the overall salary level is to a great extent inflated by political clout, rather than how the market values their skills.
I think if the education segment were exited by gov't and made more market-sensitive, that the following would occur:
* An upheaval in the composition of the teaching personnel
- Deadwood has to move on
- Parasitic bureaucrats whacked
- Quality teachers move up (pay, responsibility, status, etc.)
- A whole new contingent of folks enter the teaching market who were previously barred due to cert barriers and/or disgust with the gov't & union shenanigans
* The average salary would rise, with the departure of the aforementioned deadwood & parasites
