“In the United States you're not allowed to talk about class differences. In fact, only two groups are allowed to be class-conscious in the United States. One of them is the business community, which is rabidly class-conscious. When you read their literature, it's all full of the danger of the masses and their rising power and how we have to defeat them. It's kind of vulgar, inverted Marxism. The other group is the high planning sectors of the government. They talk the same way — how we have to worry about the rising aspirations of the common man and the impoverished masses who are seeking to improve standards and harming the business climate. So they can be class-conscious. They have a job to do. But it's extremely important to make other people, the rest of the population, believe that there is no such thing as class. We're all just equal, we're all Americans, we live in harmony, we all work together, everything is great.”

Remarks on Hannity & Colmes (30 November 2004), quoted in

Context: When you're allowed to exist on the same continent of the United States of America, protecting you with a nuclear shield around you, you're polite and you support us when we've been attacked on our own soil. They violated that protocol. … They better hope the United States doesn't roll over one night and crush them. They are lucky we allow them to exist on the same continent.

Ideology and Utopia (1929)
Context: In general there are two distinct and separable meanings of the term "ideology" — the particular and the total.
The particular conception of ideology is implied when the term denotes that we are sceptical of the ideas and representations advanced by our opponent. They are regarded as more or less conscious disguises of the real nature of a situation, the true recognition of which would not be in accord with his interests. These distortions range all the way from conscious lies to half-conscious and unwitting disguises; from calculated attempts to dupe others to self-deception. This conception of ideology, which has only gradually become differentiated from the common-sense notion of the lie is particular in several senses. Its particularity becomes evident when it is contrasted with the more inclusive total conception of ideology. Here we refer to the ideology of an age or of a concrete historico-social group, e. g. of a class, when we are concerned with the characteristics and composition of the total structure of the mind of this epoch or of this group. Although they have something in common, there are also significant differences between them.
