This is getting a little absurd. First, I'm specifically referring to the Feds in its tight control of the money supply during the Depression. They restricted the money supply. If you have another term for what the Feds did (note the difference between the Feds and the federal government), then so be it.
Loose monetary policy during a drought is not just supported by Keynesians (who really emphasize more expansionary fiscal policy), and is definitely not a 100% Keynesian view. Monetarists, for instance, support it widely. As do other economists. Friedman supported it, as does Bernanke, Greenspan, Summers, Mankiw, et al. To claim that an expansionary monetary policy is 100% Keynesian is just absurd and distorts the positions of other economists.
