Industry and academia hire people because they HAVE been at college and have a degree to prove that they did so successfully. If this system would not work than industry would press for change (hence the many new study topics that came with the rise of computers and new media).
That was the employer view. The student might view it quite differently. If you go to college and study some obscure semi-scientific subject (NO! I do not want to mention one explicitly ;-) )than you are qualified to work in that particular field. It will not help to get you into a lawyers firm or a scientific institution. But college students are (at least here) grown-ups which are free to waste their life on anything they want. If you believe that college is nothing for you: don't go. But do not request access to jobs where the employer demands a college degree.
Let's not misrepresent his argument here. He's not talking about employer requirements, but more specifically about state licensing requirements. I might want to
be a lawyer without going to law school. Wolfram and Hart might want to hire me to work as a lawyer without my having gone to law school. In California, Virginia, Washington, and a few other jurisdictions, they could hire me and train me themselves for a couple of years, after which I can take the Bar exam and start practicing law for them. (Granted, Wolfram and Hart would probably be fools to want to go this way and pay "training wages" instead of hiring a fully-qualified J.D., but there's no law that says senior partners can't be fools.)
It's the state of Florida -- or Pennsylvania, or Alabama, or whatever -- that says that this can't happen. It could be thought of as the state overstepping its boundaries, by telling W&H and I what we can and can't agree to do by ourselves.
Similarly, I can't go to work for my father's medical practice and become a brain surgeon just by helping him out, even if both he and I want it.
The problem, of course, is that I don't see any tremendous demand on the part of employers for these alternative routes; I've never heard of hospitals calling for a relaxation of training standards for doctors (or even for nurses, which
are in a critical shortage). The people who do the hiring are, as you point out, the ones who ultimately drive the trainin standards. If more people wanted non-degree-qualified nurses, there would be a recognizable demand. Hospitals and law firms hire from schools because they believe (contra Dustin) that formal education
does produce measurable benefits, and that autodidacts can't cut the mustard.
So I'm afraid that my response to Dustin is the same as it is to the other whiny students that start criticising the curriculum. "You're not in a position to have an informed opinion on the validity of the curriculum. The people who
are in such a position -- disciplinary experts and subject-matter clients --
want this formal curriculum, and have repeated stated their preference. I'm afraid that I have to go with the experts and clients on this."
