I think the best way to fund colleges, would be for the student to agree to pay the college, say, 10% of their gross earnings for some period after graduation.

It will never happen, but that's a really interesting idea.

Now:
Student: I want to major in Swedish 17th Century Folk Art.
College Advisor: Sounds good. Sign here.

Under your plan:
Student: I want to major in Swedish 17th Century Folk Art.
College Advisor: Ah...no. That wouldn't be productive. Try again.
