I'm inclined to think that there ought to be a four year college degree that teaches a number of different trade skills as part of its core curriculum. A student in such a program might take history and mathematics courses similar to other college students, but would also learn concrete skills like welding, electrical wiring, HVAC, etc. The goal would be to have a graduate that might be able to find work in a variety of different trades, not just one particular one, and also provide graduates with some of the more traditional educational breadth associated with university.
University ought to make you a more rounded person, and a better citizen, and it ought to make you more employable, all three.
