so, uh, yeah. Trade school is great, if you just want to make money. but your earning power has little to do with your 'class' I think; in many ways, getting a degree that doesn't qualify you for a job is conspicuous consumption.
What could be more conspicuous than spending a hundred grand on "self actualization" - the only outward effect basically being more interesting at parties?
be concrete. You are still speaking of internal changes; and I'm asking, "what does that mean?" - how does a person's behaviour improve after getting, say, an art history degree?
For art, you need creativity. People tell artists that "the best way to paint/write/draw/act/sculpt better is to go out and experience the world." Well, in the same way a degree in the sciences offers a good topical coverage of the knowledge the world has to offer, a liberal arts degree offers a pretty good topical coverage of the experiences the world has to offer, so you can decide what to dig into. They're useful from that perspective.
