Anybody else think the modern university system is grossly inefficient? Most of the people I knew in undergrad spend most of their time drinking to excess and skipping classes. In addition, barely half of undergraduates get their B.A in 6 years after starting. The whole system is hugely expensive in both direct subsidies and opportunity costs.
I think that society would benefit from switching to computer based learning systems for most kinds of classes. For example, I took two economics courses that incorporated CBL elements, and I found them vastly more engrossing and much more time-efficient than the lecture sections. Instead of applying to selective universities (which gain status by denying more students entry than others) people could get most of their prerequisites out of the way in a few months with standard CBL programs administered at a marginal cost of $0.
Yep. They mainly persist as a way to sort workers: those that can get through, and with a degree in X at university Y, are good enough to be trusted to job Z (even though, as is usually the case, nothing in X actually pertains to Z -- you're just signaling your general qualifications for being taken on to do job Z).
Having the degree is a good proxy for certain skills like intelligence, diligence, etc. Why not test for intelligence directly? Because in the US and most industrialized countries, it's illegal, so they have to test you by proxy -- let the university give you an IQ test as a standard for admission, but not call it that.
Shifting to a system that actually makes sense is going to require overcoming a lot of inertia.
I agree with this analysis to some extent. I'm not sure I'm willing to grant that the primary purpose of universities is a way to sort workers, but that is a major thing they're used for, and I tend to argue at length that they should get out of that business. I argue as much as possible against student evaluation, grading, and granting degrees. One of the first arguments that pops up tends to be, "But how will people know who to hire / let into grad school?"
But I don't think it's the University's job to answer that question.
