Workers, Machines and Constant Change
Anyone who drives on the nation’s toll roads has used a job-eliminating device: electronic tollgates.
Unemployment due to new technologies – and workers’ resistance to them – are as old as the industrial revolution. In the early 1900s, glassblowers were replaced by mechanized bottle makers. Today, autoworkers are no longer necessary to bolt car parts to carriages – robots do it with speed and precision. Toll takers are the latest disappearing breed.
Workers who lose their jobs to progress face painful transitions, and pessimists throughout history have warned about technologies increasingly rendering human effort obsolete. Indeed, jobs can seem to vanish overnight after an entire industry or occupation adopts a laborsaving machine, presenting displaced individuals with difficult choices. They must either invest in a new skill or move into a low-skill, lower-paying job.
But in the long arc of history, technology is continually creating new jobs to replace the old ones.
“The cycle of job destruction and creation has produced a labor force where, over the long run, workers have generally found jobs – albeit jobs that largely did not exist 100 years ago,” concludes the Center for Retirement Research in the first of three reports on technology’s impact on older workers for the Retirement and Disability Research Consortium.
The changing nature of work encourages new forms of growth by expanding the economic pie. For example, about a third of U.S. workers used to be on the farm before being largely replaced by agricultural machinery like combines and threshers, the report said. But during and after World War II, new technologies adopted by industry supplied manufacturing and office jobs to the farmers who had migrated to the cities to work. Wages rose and the economy grew rapidly during this period of unprecedented abundance.
Another way that technology helps the economy is by making goods cheaper to produce and buy, freeing up demand for other products. For example, Americans spend 15 percent of their budgets on food – less than half of what they spent in 1900 before farms became fully mechanized. More money for cell phones. …Learn More
