Common sense was the first victim

The chief benefit of designing societies on the basis of market-based decision-making is the inclination for markets not to suffer stupid decisions for long. The assumption is that people empowered with fulfilling their own self-interest will not allow for much nonsense. Certainly the chief exponents of rational decision-making in the markets, the economists themselves, could be relied upon to render clear and unbiased judgments about the proper state of affairs in a society. So goes the reasoning. 

The irony of the entire enterprise of neo-classical economics is how craven were the economists themselves. Long before the entire finacial system collapsed in 2008, the economists became ideologues who used their status in society to promote an ideology they couldn't help but know wasn't working. The nonsense the market economists are and were spewing is the greatest indictment of the theo-classical economic system. 

Common sense was the first victim of these 'rationalists.' It turns out they are no less prone to promoting garbage than the promoters of any other system.
