Same holds with bad-mouthing Bush, Republicans or business. "I don't understand a thing he says but, since he opposes capitalism/Bush/Kyoto/IMF/Republicans, it must be because he is sooo intellectual!" THat's what they learn at their state university and, the unwashed [but easy] coeds they pick up enforce the perception.
He missed it because Thorstein Veblin already said the same thing in "The Theory of the Leisure Class". It's Veblin assertion that the people assume "Leisure Class" attitudes about things like the environment, social welfare, foreign policy etc. People adopt additudes and ideas that make them feel superior to the unwashed rabble.
