I haven't watched any of the Zeitgeist documentaries before, only seen a clip from the second one when they interviewed John Perkins. The Zeitgeist docos are great at opening up monetarism; but like alot of fundamentalist economic models, are plain impractical. So Marxist Socialism, Austrian School Libertarianism, the ever contradictory Chicago School predatory capitalism, and now the Zeitgeist Movement all exist in their little theory bubble instead of being functional in the real world.
So the Zeitgeist Movement like Ayn Randian principles believe that the world will just grow and develop without the soldier ants, this time with Zeitgeist the 'robots' magically appear and do all the grunt work so that all of us can sit back and let the robots spoon feed us caviar and top up the champagne.
