The government does not guarantee Fannie Mae or Freddie Mac, but the widespread assumption has been that the government would step in with a bailout to prevent chaos in financial markets.

Alan Greenspan, then head of the Federal Reserve System, made the same point in testifying before Congress in February 2004. He said: "The Federal Reserve is concerned" that Fannie Mae and Freddie Mac were using this implicit reliance on a government bailout in a crisis to take more risks, in order to "multiply the profitability of subsidized debt."

Chairman Greenspan added his voice to those urging Congress to create a "regulator with authority on a par with that of banking regulators" to reduce the riskiness of Fannie Mae and Freddie Mac, a riskiness ultimately borne by the taxpayers.

Fannie Mae and Freddie Mac do not deserve to be bailed out, but neither do workers, families and businesses deserve to be put through the economic wringer by a collapse of credit markets, such as occurred during the Great Depression of the 1930s.

Neither do the voters deserve to be deceived on the eve of an election by the notion that this is a failure of free markets that should be replaced by political micro-managing.

If Fannie Mae and Freddie Mac were free market institutions they could not have gotten away with their risky financial practices because no one would have bought their securities without the implicit assumption that the politicians would bail them out.

It would be better if no such government-supported enterprises had been created in the first place and mortgages were in fact left to the free market. This bailout creates the expectation of future bailouts.

Phasing out Fannie Mae and Freddie Mac would make much more sense than letting politicians play politics with them again, with the risk and expense being again loaded onto the taxpayers.
