If teachers are so well paid for easy work, how come the education majors are supposedly the dumbest, not the smartest college students? Why would anyone with a 120+ IQ choose to become an engineer, attorney, or doctor, if teachers are the best paid professionals around?
Doctors and lawyers can make a lot more than teachers. As for engineers, it's a good question; probably a fair number don't make 70K although a lot make that or more. It probably comes down to people following their interests rather than what they perceive as the easiest route to a degree.
Besides, the education school curriculum these days is insufferable for anyone who is not a committed socialist.
Hey, that's my secret. :)
