You could theoretically switch to a system where there is a standardised national exam at degree level in subjects such at computer science. Then instead of paying lots to go to a fancy college you could learn inexpensively and still get as impressive a qualification. Dunno if it's a good idea. In the UK there are standardised exams at 18 so if you get 3 As at A-level people know your bright regardless of where you went, in fact it's probably harder to do that at a rubbish school. At university level though you don't have that so a degree from Oxford is probably going to be valued more than one from Bedfordshire, say even if the grades are similar.
I like the exam idea but it's not really the best way to test the skill of a person. You wouldn't hold an exam for the best painter or the best sculptor. I feel like computer programming (and related jobs) in general is similar.
If you watch the TV show Better Call Saul (strongly recommend), you see him in the last episode learning that his own lawyer brother doesn't want him working at the same firm because he did an online law school, instead of going to a prestigious law school.
there is no good reason why there can't be meaningful standardised exams for post secondary education. professional bodies set exams at this level in accounting, engineering etc. it would be a much more efficient model.
