While the author clearly values the liberal arts (um, it's McSweeney's), there's something to be said for actually getting things done in the world. A lot, actually.
What the author is parodying is less the degree itself but more the miles wide and inches deep approach to education and life that many intelligent people are fond of taking.
I've been guilty of this, and satire is usually born of familiarity, so I assume the author has been as well. The point is, recognize that pursuit of education as amusement and status symbol is a hobby done for you and none other, and if you want to make some kind of impact outside of your own head, you're going to either have to get deeper and more focused or get more pragmatic.
