For those who know more about economics than I do, I saw a video of Milton Friedman discussing the Great Depression and the Federal Reserve's role in it, and he was saying that it is not the proper job of the Federal Reserve to control interest rates, but it is the Fed's job to control the supply of money, and that when people rushed the banks and they couldn't give people their money, that the Fed should have expanded the money supply so that people would see that they could get their money, and if people saw that they could get their money, then no one would have have tried to take it and there would be no rush.

It doesn't sound quite right, and I've heard Ron Paul and other Austrian economists says that the Federal Reserve shouldn't control the money supply either. Would someone mind clarifying for me?
