I think we've slapped a college degree requirement on too many jobs. Some due to that employers can't give pre-employment tests any more, some due to that a HS diploma means absolutely nothing other than a person is 18 and breathing.
I don't think you need a college degree to teach elementary school. I certainly don't think you need a degree for any of the arts, and I don't see how a degree is required for communications.
All these jobs need training beyond HS, but not a 4 yr degree, something more like two years of OTJ mixed with some classroom instruction.
