Market totalitarianism is the creeping advancement of corporate capitalist control over all the details of modern life, in and across its three major spheres — work, politics, and personal life.
If you doubt this phenomenon is real, consider this fact, as mentioned, all the way from Australia, by TCT commenter Luis Cayetano: In May of 1958, Erich Fromm was interviewed at length on commercial television in the United States.
52 years later, that same thing is so far from being possible, it is almost unimaginable. Picture 60 Minutes, for example, devoting not just one but two segments (see the run-time of the Wallace interview of Fromm) to letting, say, Noam Chomsky explain his present view of the society and the world.
No fucking way that happens now, obviously. Sponsors these days, having grown all the more powerful and having learned well the dangers of unpoliced television, would never permit it, and the producers and reporters, knowing that, would never in a million years propose it.
