If you have a pool of applicants for a job, all with no relevant experience, it's an easy filter. You filter out all the people who haven't proven they can do something they agreed to do for 3/4 years.
I.e. one enrolls in a privately-owned, for-profit universities if they have the money, but don't want to work their arse off to get a degree, or don't have good enough grades from the secondary education to qualify for public unis.
