ICT teaches computer use, not industry skills
With the stuff they teach in schools these days it is like complaining that driver education does not encourage the right people to become diesel mechanics.
Look at the stuff they teach in most schools: a bit of word processing, spread sheeting, how to find stuff on Wikipedia then copy/paste etc.
That, and their proficiency in fiddling with the settings in their Facebook profile, is about the limit to their exposure. From that most kids, their parents and school system give career advice.
"Johnny, you're so good at making the computer do things. You are a computer whizz. You will do great at Computer Science."
No wonder computer science has one of the highest first year drop out and failure rates. The students have no way to measure their aptitude before starting at university.
