The Warrington College of Buisness at the University of Florida requires applicants to have two years of on the job experience after their undergrad schooling before being considered for acceptance.
I'll bet you wouldn't find too many students drinking themselves to death in fraternity hazing rituals on our college campuses if they had been required to drive a truck or work at Wal-Mart for two years before going to school.
Come to think of it, there wouldn't be too many fraternities, period.
