Judging from some comments I've seen in the various blogs, I wonder if they bother teaching that simple truth in all these IT trade schools.

Not that they are bad. A friend of mine went off to one of the first IT trade schools when I went off to college. He landed a great job and has moved up in IT management since he started, eventually getting several degrees along the way.

But that was a VERY long time ago and recently another friend who was teaching at one of the trade schools resigned because he was being pressured to give passing grades to everyone.
