When the bubble finally bursts completely, millions of Americans will be looking for someone to blame. Look for Congress to hold hearings into subprime lending practices and “predatory” mortgages. We’ll hear a lot of grandstanding about how unscrupulous lenders took advantage of poor people, and how rampant speculation caused real estate markets around the country to overheat. It will be reminiscent of the Enron hearings, and the message will be explicitly or implicitly the same: free-market capitalism, left unchecked, leads to greed, fraud, and unethical if not illegal business practices. But capitalism is not to blame for the housing bubble, the Federal Reserve is. Specifically, Fed intervention in the economy-- through the manipulation of interest rates and the creation of money-- caused the artificial boom in mortgage lending.
