He cut spending because the war ended, Frank. Truman did the same thing. That's a negative supply shock. We then boomed by adding manufacturing to resupply and rebuild Europe. That's a positive supply shock.
We cut taxes years later.
In 1920 unemployment had spiked from 4% to 12% as GDP collapsed 12%.
That's what happens when wars end. Sounds very 1946ish, Frank.
And that's with a collapse in the monetary base in 1920-21 on par with 1929-30!
Perhaps you can explain why you think the MB collapsed in 1920, Frank.
Between 1933 and 1939 the portion of GDP attributable to government grew by 50% while unemployment averaged 20%. In contrast, Harding cut spending 50% and unemployment falls from 12% to under 3%
It's funny how you continue to skip over THIS:
Year %GDP Private investment
1930 -8.6% -33.3
1931 -6.5% -37.2
1932 -13.1% -69.8
1933 -1.3% 47.3<--FDR takes office. First Banking act and other early reforms are passed.
1934 10.9% 80.6
1935 8.9% 85.2
1936 13.0% 28.2
1937 5.1% 24.9
1938 -3.4% -33.9
1939 8.1% 28.6
1940 8.8% 39.3
But I don't blame you. I'd run from those facts too if I were you.
