"The U.S. Census Bureau reports that 2011 manufacturing output grew by 11 percent, to nearly $5 trillion. Were our manufacturing sector considered a nation with its own gross domestic product, it would be the world’s fourth-richest economy. Manufacturing productivity has doubled since 1987, and manufacturing output has risen by one-half. However, over the past two decades, manufacturing employment has fallen about 25 percent. For some people, that means our manufacturing sector is sick. By that criterion, our agriculture sector shares that “sickness,” only worse and for a longer duration."
