As long as the PTB have an endless supply of energetic, inspired, idealistic young people coming out of college who are willing to work cheap and commit to a few years of tirelessly trying to "make a difference" (TFA) and a whole lot more of energetic, inspired,idealistic young people coming out teacher's colleges who innocently give it their all (working "cheap") for a few years and quickly burn out, the system will chug right along. A significant improvement in the economy could slow it right down. There are many, many, teachers out there ready to jump ship at the first opportunity. If the economy improves, many of those recent college graduates won't have to join TFA to enhance their resumes. They'll have jobs waiting for them. Maybe then they'll have to start listening to those of us who are determined to make teaching a real "profession" again. What do you think? Could that happen?
