That's an amusing analogy, but it's conflating university as a purely academic pursuit (learn these things in order to know the things) with university as vocational training (learn these things so you can get a job.) As people have to pay for their degree through loans now, people see it as a means to get the career they want. It's not learning any more. It's training.

So, to continue the analogy, a degree is the equivalent of a forklift truck license, and people do want to drive their forklift truck to the gym. Because they're paying to be able to do that.

Undergraduate degrees are not vocational in any of the leading universities in any field. They are sometimes a prerequisite to vocational training, but aren't one in and of themselves.

There's a pretty good reason for that - the base assumption is that training in fundamentals, methods and ways of thinking is something you won't get anywhere else.
