Twice the salary of working people? WTF? Are you implying that teachers don't work?
Let me give you a personal example. My mom was a public school first grade teacher. She worked for 30 or so years and when she retired about maybe 7 years ago she was making $37,000 a year. She has a master's degree plus 45 credits in education. During the school year, she worked M-F from 7:30 AM until about 8 PM typically. She worked usually something like 10 hours a weekend during the school year. During the summers she would typically take about 2 weeks off to take me and my brother camping or something like that, but other than that she would be working maybe an average of 5 hours a day. All told, she certainly worked more hours a year than your typical worker in most industries. Out of that $37,000 a year, she spend something like $5,000 out of her own pocket on supplies the school couldn't afford, buying things like jackets for kids who couldn't afford them, and covering other miscellaneous expenses for field trips and that kind of thing. She wrote the math curriculum for the entire state and then developed a reading program for kids with developmental disabilities that has had two Phd. dissertations written about it, has been written up in a number of national magazines, and has been adopted by about a dozen school districts around the country. She is retired now, but she still spends several weeks each year working on updating the reading program on her own time and sending the updates around to the schools that have adopted it. She was chosen for the teacher of the year award for the state, but she turned it down because she didn't like people making a big deal out of her. She has pulled kids out of abusive home situations, she has gone over to kids' houses at night when their parents were out of the picture to cook them dinner, and all kinds of other stuff like that. She is one of the smartest, hardest working, people I know. Were she in the private sector she would easily have been making six figures. Probably high six figures.
So when I hear people ranting about how it isn't really work and they're paid too much... Well, it just fills me with disgust. What an awful, cruel, ignorant, thing to say. For shame.
