Sadly, this is something that most junior-high students can understand, yet appears to be beyond the grasp of most politicians.
It just ain’t so – Walter Williams: 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.
In 1790, 90 percent of Americans did agricultural work. Agriculture is now in “shambles” because only 2 percent of Americans have farm jobs. In 1970, the telecommunications industry employed 421,000 well-paid switchboard operators. Today “disaster” has hit the telecommunications industry, because there are fewer than 20,000 operators. That’s a 95 percent job loss. The spectacular advances that have raised productivity in the telecommunications industry have made it possible for fewer operators to handle tens of billions of calls at a tiny fraction of the 1970 cost.
