"The “democratic” system of the West has evolved mechanisms for deflecting rebellion that are far more sophisticated and effective than any that existed in the Soviet Union. It is a truly remarkable fact that in modern Western society people “rebel” in favor of the values of the very system against which they imagine themselves to be rebelling. The left “rebels” in favor of racial and religious equality, equality for women and homosexuals, humane treatment of animals, and so forth. But these are the values that the American mass media teach us over and over again every day. Leftists have been so thoroughly brainwashed by media propaganda that they are able to “rebel” only in terms of these values, which are values of the technoindustrial system itself. In this way the system has successfully deflected the rebellious impulses of the left into channels that are harmless to the system."
