The government began heavy military spending in 1940, and started drafting millions of young men that year; by 1945, 17 million had entered service to their country. But that was not enough to absorb all the unemployed. During the war, the government subsidized wages through cost-plus contracts. Government contractors were paid in full for their costs, plus a certain percentage profit margin. That meant the more wages a person was paid the higher the company profits since the government would cover them plus a percentage.<18> Using these cost-plus contracts in 1941-1943, factories hired hundreds of thousands of unskilled workers and trained them, at government expense. The military's own training programs concentrated on teaching technical skills involving machinery, engines, electronics and radio, preparing soldiers and sailors for the post-war economy.<19>
Structural barriers were lowered during the war, especially informal policies against hiring women, minorities, and workers over 45 or under 18. (See FEPC) Strikes largely ended as unions pushed their members to work harder. Tens of thousands of new factories and shipyards were built, with bus service and nursery care for children's forecast making them more accessible. Wages soared for workers, making it quite expensive to sit at home. The combination of all these factors drove unemployment below 2% in 1943.<20>
http://en.wikipedia.org/wiki/Great_Depression_in_the_United_StatesMyth: Tax cuts spur economic growth.
Fact: High tax rates are correlated with economic growth.
The U.S. emerged from World War II as the world's only economic superpower. From 1947 to 1973, it experienced phenomenally high growth; the GDP grew at an average of 3.4 percent a year. The top tax rate remained between 88 and 91 percent until 1964; afterwards, the rate was reduced to 70 percent, still stratospheric by today's standards.
The economy slowed down after 1973, for reasons that economists are still debating. But what is not debatable is that taxes started falling for the rich in 1978 (with a capital gains tax cut). Reagan accelerated these cuts with a vengeance: the top income tax rate was slashed from 70 to 28 percent. Bush and Clinton raised them somewhat, to 39.6 percent today. But that is still roughly half of what it was during the 50s and 60s.
