Yeah. What Zander said. You have cited two examples where such spending did not work.
We can add Japan in the 1990s where the gov't passed stimulus after stimulus and kept rates at near zero and the economu is still in recession.
Yeah... totally didn't work...
1933 to 1936
GDP: Increased from 56.4 billion to 83.8 billion
Personal consumption: Increased from 45.9 billion to 66.2 billion
Unemployment: Fell from 25% to 15%
1940 to 1945
GDP: Increased from 101.4 billion to 223.1 billion
Personal consumption: Increased from 71.3 billion to 120 billion
Unemployment: Fell from 15% to 5%
And you know why Japan never got out of it's hole? Just as the economy began to recover, they'd listen to idiots like you and slash spending to the bone in an attempt to balance the budget.
