Those digging in with the ego & power trip line, my experience is almost entirely at odds with that viewpoint. Whether in training or line flights, the trainers I've flown with have been excellent (with a couple of notable exceptions, but they are exceptions), and no power trip has been evident. I think it's unfair to paint the training department with such a broad brush.
I take the point though that the only way to effect significant change is by mass resignations.
