Which is absolutely true though not particularly relevant. There's a whole bunch in the middle there with no great aspirations, but nevertheless perform a valuable contribution to the community, no matter how menial. When I was conducting job clubs, my first task was to build the self-esteem they needed to actually go out there and do the necessary to find useful work; self-esteem that teachers had gone to some trouble to eliminate. For someone whose background is two generations on the dole, any kind of a regular paying job is a great achievement.
No matter how well-qualified they are and experts in a certain area, nothing gives teachers the right to destroy the aspirations of those they are supposedly committed to help.
