Hate to think you're right, man. Education is so fundamentally important, it would be a shame to think it's in the wrong hands. For what it's worth, I know more truly fine examples of educators by far than miserable ones. (Though come to think of it, I know a frightening lot of miserable ones too, despite a lifetime of trying to avoid them.)
Perhaps expertise in education is like any other field. There are operators trying to work the system, and there are pretenders, and there are also many sincerely dedicated people, plus a few geniuses and leaders, and there is a lot of deadwood. Some fields are so exacting that deadwood has little place. So it is in computer science and software engineering, for example. Perhaps in education it's naturally more forgiving, more relaxed. Given a choice between the two, teachers would rather cultivate a learning environment than bring out the rule book, wouldn't they? Perhaps that makes it relatively easy to hop on board and get a free ride, I don't know. How would one fix that?
