The point of college is to teach stuff, not to separate people into "success" and "failure" bins. We don't actually know that. A lot of college degree is the signalling factor. How much is up for debate.

Would people still go to college for the education if the signalling aspect was stripped out? (You could have third-party assessment tests, of course.) I'll also exempt doctors and lawyers for now.
