There were examples of rabid conspicuous consumerism in Terry Southern’s The Magic Christian (I have only seen the 1960s filmed version, never read the book) and Ivan Stang’s 1970s pre-Bob Dobbs subterranean clown world “future” (http://www.youtube.com/watch?v=FHx2nLFMAzE).
I have an old book on “the madness of crowds”. The behavior is nothing new (even if it is rude).
Yes, it’s nothing new. You should have been in the Eastern Block when the Berlin Wall fell (heck, even before.)
I did enjoy that movie when it came out.
