From Walter E. 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.
For the most part, rising worker productivity and advances in technology are the primary causes of reduced employment and higher output in the manufacturing, agriculture and telecommunications industries. My question is whether Congress should outlaw these productivity gains in the name of job creation. It would be easy. Just get rid of those John Deere harvesting machines that do in a day what used to take a thousand men a week, outlaw the robots and automation that eliminated many manufacturing jobs and bring back manually operated PBX telephone switchboards. By the way, if technological advances had not eliminated millions of jobs, where in the world would we have gotten the workers to produce all those goods and services that we now enjoy that weren’t even thought of decades ago? The bottom line is that the health of an industry is measured by its output, not by the number of people it employs.
