Jjoe, not sure where you learnt, certainly sounds like you had a bad experience!
I have taught at a number of schools over the years, good bad and indifferent, even the bad one, run by a real shark, did not "screw the incumbents",though that one did push through one guy who should not really have been allowed near an aircraft, he had the ability but wrong mental attitude, but generally even there the students were dealt with in a professional manner and I would say the schools that do screw students are very much in the minority.
