- Other industries pay their best employees more, so it must work.
- Students will perform better if their teachers are more motivated, and teachers are motivated by more money.
While I can think of a lot of reasons why No. 2 is completely false, I'd like to share the following article by Peter Greene that completely debunks No. 1:
Every profession accepts merit pay. All people in the Real Working World accept having their income tied to their job performance. Why should teachers be any different? That's the standard line. Only it isn't true. Here's a quick report from the Bureau of Labor Statistics.
I'd also like to point out that a friend of mine is married to a man who works on straight commission in construction sales. That means that he doesn't make any money if he doesn't sale anything. When contractors are building, he makes a commission on millions of dollars in sales.
