I think this is one of the better quotations from the article:
To me, liberal-arts education is as ineffective as it is now not chiefly because there are a lot of strange theories in the air. (Used well, those theories can be illuminating.) Rather, it's that university culture, like American culture writ large, is, to put it crudely, ever more devoted to consumption and entertainment, to the using and using up of goods and images. For someone growing up in America now, there are few available alternatives to the cool consumer worldview. My students didn't ask for that view, much less create it, but they bring a consumer weltanschauung to school, where it exerts a powerful, and largely unacknowledged, influence.
