Outsourcing is a new name for a long-standing phenomenon: the movement of jobs from the USA to countries where wages, benefits and the cost of living are much lower. In the 1970s and 1980s, heavy manufacturing jobs went to other countries by the tens of thousands. The result was cheaper goods for U.S. consumers and less pollution in many of the nation's industrial cities. Economists who backed the trend envisioned a new "knowledge economy" in which well-trained Americans would become the world's designers, innovators and administrators. The dirty work would be sent overseas.
