You don't go into teaching to make a lot of money, unless you can tutor rich kids maybe then.

From my experience people go into two teaching for one of two reasons.
1. They want to be teachers, they want to shape the next generation or whatever. (the good kind of teacher)
2. They couldn't hack it in their chosen degrees in college so they slid into the easy degree, education. (the kind of teacher that belongs at McDonalds or digging ditches or whatever menial labor job they can get)

I have only heard one of those types bitch about their pay. If it takes you more than one guess to figure it out, you were probably taught by the ones doing the bitching.
