U.S. Social and Economic History in Music

We forget this was once a very optimistic country -- at least for my parents.
Repressed and extremely horny, but still optimistic...
Heavy (post Bretton Woods, post '74 embargo, "peak oil") disenchantment begins...

Reagan (war for the sake of war) fear compounds disenchantment...
Disenchantment sows (Bush/Cheney/Iraq) anarchism on the cusp of The Great Depression II Recession -- that corporatists will strive to blame Obama for (as Reagan once successfully blamed Carter).
So the question is: will the stupid, fake growth lie work again?  And what will it sound like?
