If everyone had a college degree the unemployment rate would be the same as it is now. Human resource professionals would have found some other criteria to winnow out the winners from the also-rans.
Many jobs which could be done by alert high school grads are being done by college grads because there is a tendency for HR people to hire the most qualified applicants who will take the job. Requiring a college degree, or even a degree from a select group of elite colleges, is a way to easily disqualify most of the applicants in a tall stack, "easily" being the operational term.
