9) Massive stimulus didn’t work in the Great Depression. As this Heritage Foundation study notes: “After the stock market collapse in 1929, the Hoover Administration increased federal spending by 47 percent over the following three years. As a result, federal spending increased from 3.4 percent of GDP in 1930 to 6.9 percent in 1932 and reached 9.8 percent by 1940. That same year– 10 years into the Great Depression–America’s unemployment rate stood at 14.6 percent.” Same goes for Japan and its Great Stagnation of the 1990s.
