The capitalist "Great Leap Forward", of which we are on the brink, like its communist predecessor is an attempt to impose on reality an ideological system's claims to universal truth, regardless of the underlying reality. The Maoist conceptions of "collectivization" and "industrialization", with perfect knowledge of how humans will behave in the communist utopia to come, were uninterested in the realities of how millions and millions of Chinese actually got their daily rations. Somewhere between 20 and 50 million people had to die to kill this vision.
The capitalist conception of "efficient markets" and "rational expectations", with perfect knowledge of how humans will behave in the "free market" utopia upon who's brink we teeter, are uninterested in the realities of how millions and millions of Americans and Europeans get their daily rations. So committed to their utopia are mainstream economists that they take it upon themselves to scold the reality based community for it's sinful insistence on reality.
Shut down the government, cut off social security, medicare, medicaid, food stamps and other income supports. These all offend the free market utopia. How many will need to suffer how much to prove the insanity?
