Don't confuse me with Schmitty. I have admiration for teachers and some of the stuff they do. I think most people can look back at their life and pick out at least a couple awesome teachers.
With that being said, it's simple economics, supply and demand. Right now, there is a ton of supply relative to demand. That has resulted in the profession being over paid. I assume you either don't understand economics and free trade or you choose to ignore it. It also demonstrates the inefficiency of a public school system and really everything publicly ran.
The only way to correct teachers being overpaid is to either raise the standards to basically trim down the supply side, or lower wages. Like I said, it's very simply supply and demand. To ignore economics is to live in fairy tail land where everyone can make $100,000.00 a year.
