[C]lass consciousness is not one of our national diseases; we suffer, indeed, from its opposite-the delusion that class barriers are not real. That delusion reveals itself in many forms, some of them as beautiful as a glass eye. One is the Liberal doctrine that a prairie demagogue promoted to the United States Senate will instantly show all the sagacity of a Metternich ... another is the doctrine that a moronrun through a university and decorated with a Ph.D. will cease thereby to be a moron.
