Good point, Ivor. The problem is that during our last period of deep deflation, the government applied the model and failed to produce anything close to a recovery. Average money supply (M1 &M2) in the 30s was twice as high as money supply in the 20s, yet that money did not find its way into credit markets or private investment. In 1939, FDR's Treasury Sec. even said that spending money had not worked and he had no idea what to do next. Perhaps he didn't have any ideas, but the Axis did.
