You conveniently left out the part of my post about local manufacturing plants which appears to cover your comments.
Again, if you hold qualifications, of any type, and decide to go into a field, such as teaching, you can't reasonably expect that sector to modify the pay because you think you deserve more.
Everyone for the most part chooses where they want to ply their trade, knowing full well the monetary compensation. To enter a field with that knowledge, then to try to change "the system" will be an exercise in futility, much larger forces than yourself control the amount of pay for a given position.
The education system in the U.S. is lacking a bit in the fundamentals of the free market and how it controls the price of products, and compensation for jobs.
