Yet America remains by far the No. 1 manufacturing country. It out-produces No. 2 China by more than 40 percent. U.S. manufacturers cranked out nearly $1.7 trillion in goods in 2009, according to the United Nations.
The story of American factories essentially boils down to this: They've managed to make more goods with fewer workers.
The United States has lost nearly 8 million factory jobs since manufacturing employment peaked at 19.6 million in mid-1979. U.S. manufacturers have ranked near the top of world rankings in productivity gains over the past three decades.
That higher productivity has meant a leaner manufacturing force that's capitalized on efficiency.
