Get Your American Optimism Here!

General Motors in the 1939 World's Fair in NYC presents a vision of the future in which ... surprise surprise, cars are ubiquitous.
But is that really all there is to American Optimism?
Corporate visions are fine and dandy - in fact, this was a very successful piece of envisioning. Even today few futuristic movies show anything so pedestrian as people walking... (Or the resultant obese drivers, for that matter. Perhaps this is also American Optimism?)
LINK BONUS: Lileks is not Defrosted Angry Neocon. Perhaps because today he is Defrosted Optimistic Neocon? No, turns out he's depressed. How unamerican.
