There's been a lot of ink spilled lately about ending the expectation that everyone should go to college. I'd like to see more about how everybody is expected to stop learning after that, unless they're looking for more degrees (or the ubiquitous MBA in marketing/finance), and especially if they have a good job.
I think that the main reason is because a la carte education would collapse its awful pricing structure. Having the majority of your student body not tied to your university for their entire future would end up confusing and improving a lot of things IMO. I'd love to shop by professor, and arbitrarily retake courses of study in my adult life if I feel I'm getting rusty.
