Starry-eyed grads are actually one of the worst part of the TFA program. The idea that one is engaging in some awesome, progressive action is emphasized, while the actual reality, and drudgery, of teaching is not. Thus, you end up with people entering, thinking they will change the educational system by two years in an underserved school, look around and say "Oh, this is bullshit."
I thought that was the point. To get the starry eyedeness out of people, and introduce them to the real world. That is why they recruit specifically from the starry eyed, by using all the progressive BS.
