Russ Roberts of George Mason University has written a very good article for the Mercatus Center explaining – for economists and non-economists – how government intervention created distortions in the housing and finance sectors. He also blames Wall Street, paticularly for lobbying for the policies that caused the distortions and led to the financial crisis. Here’s an excerpt from the executive summary:
Some blame capitalism for being inherently unstable. Some blame Wall Street for its greed, hubris, and stupidity. But greed, hubris, and stupidity are always with us. What changed in recent years that created such a destructive set of decisions that culminated in the collapse of the housing market and the financial system? …public-policy decisions have perverted the incentives that naturally create stability in financial markets and the market for housing. Over the last three decades, government policy has coddled creditors, reducing the risk they face from financing bad investments. Not surprisingly, this encouraged risky investments financed by borrowed money. The increasing use of debt mixed with housing policy, monetary policy, and tax policy crippled the housing market and the financial sector. Wall Street is not blameless in this debacle. It lobbied for the policy decisions that created the mess. In the United States we like to believe we are a capitalist society based on individual responsibility. But we are what we do. Not what we say we are. Not what we wish to be. But what we do. And what we do in the United States is make it easy to gamble with other people’s money—particularly borrowed money—by making sure that almost everybody who makes bad loans gets his money back anyway. The financial crisis of 2008 was a natural result of these perverse incentives. We must return to the natural incentives of profit and loss if we want to prevent future crises.
