Because employment is controlled by the necessity of mickey mouse teaching certificates and teachers' unions. That constitutes an economic cartel, which artificially inflates prices, in this case wages.
The proof is in looking at private schools, which are not bound to hire only those with certificates or union membership. Wages are much lower there and quality is much higher.
We've already established that teacher unions are not a factor in every state, yet there are public schools in Texas and NC. Keep beating that horse, but I'll not redress it.
I will conceed, even though you have no proof, that teachers in private schools make less than teachers in public schools. But this doesn't really support the argument that public school teachers are paid too much, rather, it supports the arguement that private school teachers are paid too little.
Quality is MUCH HIGHER in private schools: Probably a subject for another thread, but frankly I don't see how you could prove this since there's no yardstick that measures private education. i will conceed that SOME private schools are probably better than SOME public schools, but then, you could just as easily compare different public schools on this basis.
Go ahead and cherry pick.
Do TX and NC not require teaching certificates for employment in public schools?
How do you explain the fact that teachers in private schools, on your own admission, are both better and paid less? That would seem to be a contradiction, right? Is not the only difference between them either union membership or teaching credential required or both?
Cherry pick?
Well, excuse me for not generalising more to support your patently untrue contention that ALL teachers belong to unions and their pay is based on false markets.
Also, I conceeded that private schools generally pay less than public schools.
I did not conceed that the quality of teaching in private schools is generally better.
However, let's simply adress your contention that somehow, teacher licensing/certification creates a false market.
I assume that your theory goes something like this:
1. Teaching Jobs are only available to those with arbitrary certification, that is really meaningless
2. Certification makes me more employable than any Joe Schmow
3. Therefore, I demand to be paid whatever I feel the certificate is worth.
4. My demand will be more than private industry would pay me.
Is this about how your theory of overpaid teachers goes?
