One major cultural development over the last three decades is that the only permissible mention of “class” in the economic sense has been the utterly superfluous habit of treating oneself and others as solidly “middle class.” … The suppression of the obvious point that every “middle” needs two substantial extremes to be legitimate is an artifact of the neoliberal doctrine that there is no such thing as social class, and most decidedly, “economic” classes (working class, upper class, proletariat) do not exist. The only class in which one can safely profess membership is the “middle class,” or the class of no class. But this all-inclusive category is nervously duplicitous, because it really consists of the denial of all personal categories.
