Well built reflexion,

it is good to witness the opposite reflexion taking place in Quebec as the real value of CEGEP is periodically being questionned. Among other things, it is sometimes considered a hinderance to University level education and it is often criticized that it does not properly prepare for the employment market.

Meanwhile, we can also acknowledge a tendency of some professional orders to require ever higher level of education to perform different tasks. The best example of this would be with the different health workers professional orders; in the past ten years, Psychologist have had their requirements raised to Doctorate level, Physiotherapist require a master degree, etc.

It is quite the paradox that, while in HR classes they're teaching a philosophy very close to the one you're advocating (leaving behind the whole "silo" thinking), some field would to the contrary turn to "over-academisation".

Truth is, we define our specialities and tools trough the work we execute and there is a limit to the knowledge and preparation a school can provide an individual.
