“The housing bubble could not have arisen without the Federal Reserve. Had people started buying houses at unusually high rates, banks’ loanable funds would have begun to deplete, interest rates would have shot up, and that would have been the end of it. That would have discouraged any additional speculation in real estate. But Alan Greenspan and the Fed could create money out of thin air, thus giving the banks more to lend and driving interest rates down, thereby perpetuating the destructive bubble in housing.” -Tom Woods
