The process by which utopian visions turn out dystopian?  True Socialist Man turns into a nation of greedy criminals?  The master race ends up with cities bombed to bits?  The Great Society turns into Detroit?  The Federal Reserve System is created to control money supply to moderate boom/bust cycle and gives the prolonged boom of the 1920s followed by a ten year recession of extraordinary suffering?

Okay: there is now: transtopia.
