Most of the world has severed the two. A lot of what you'd consider key parts of the university experience just doesn't exist in most of Europe or the highly developed parts of Asia. In practice, it's attaching job training to a very, very expensive resort, regardless of who is paying for it. It's pretty nice, in the very same sense that spending 4 years in a beach resort ls also great, but one needs to be absurdly wealthy to choose this model if an equivalent was available without all the features that most of the world has abandoned. The US system would already have been in trouble years ago if it didn't have a government license for being the safest, more reliable way to immigrate into the US. Get rid of the F1 practical training to work visa pipeline, and see many US institutions in serious economic trouble. We can keep trying to keep it working as-is by pushing other people's money into the expensive vacation environment, but without major subsidies, we are already seeing more people realize that the risks are way too high when you have to get loans to attend. There is no idealism separate from economic incentive in institutions that charge 60K per year, plus often a whole lot more for mandatory on-campus housing, without financial aid.

But as it's normal with failing institutions, they'll be extended, kicking and screaming, until they completely collapse instead of reform, like almost every other country in the world already has.
