Marcuse wasn't a Jew, actually. But yeah, I don't really find the analysis convincing. I mean... amusement parks have towers, and queues, and walls round the outside, like concentration camps? And they're... organized and administered? Somehow this isn't quite getting past the laugh test. (Isaiah Berlin was absolutely outraged by the Marcuse quote, incidentally.)
Update: Marcuse was a Jew, actually. My bad. I'd misremembered this from Martin Jay's book.
