I'm very sympathetic to the idea that you don't need to go to college to get ahead or get a good job - plenty of examples of it in my family.
Having said that, there's a fine line between "not everyone wants to college" or "college is not for everyone" and "college is bad, kids shouldn't go there". I don't know about Kirk in particular, but a lot of conservative commentators tend to cross that line, and I don't think that's a good thing at all.
Take it from someone who works in the engineering world, there's not enough domestic students in some industries who obtain a college degree. It shouldn't be an either / or proposition here.
