After an undergraduate degree, and with the exception of MBAs and some doctors and lawyers, the more educated you are, the less you will get paid

Nice try. <link> Let's face it, people become teachers for some combination of the following reasons:

1. They have a calling for it, love the work, love their students and love the idea that they are shaping the future.

2. They were middling to poor scholars themselves and couldn't hack the engineering, pre-med, pre-law programs. (Or couldn't get into grad school).

3. They're willing to trade earnings for the job security, benefits and time off associated with being a civil servant.

Nothing wrong with any of that, but spare me the cynicism. If your job sucks a** man up and find another one.
