George Carlin, Jammin' in New York (1992):
Now, to balance the scale, I'd like to talk about some things that bring us together, things that point out our similarities instead of our differences. 'Cause that's all you ever hear about in this country. It's our differences. That's all the media and the politicians are ever talking about—the things that separate us, things that make us different from one another. That's the way the ruling class operates in any society. They try to divide the rest of the people. They keep the lower and the middle classes fighting with each other so that they, the rich, can run off with all the fucking money! Fairly simple thing. Happens to work.
You know? Anything different—that's what they're gonna talk about—race, religion, ethnic and national background, jobs, income, education, social status, sexuality, anything they can do to keep us fighting with each other, so that they can keep going to the bank!
You know how I define the economic and social classes in this country? The upper class keeps all of the money, pays none of the taxes. The middle class pays all of the taxes, does all of the work. The poor are there just to scare the shit out of the middle class. Keep 'em showing up at those jobs.
