One controversial side effect to global sourcing is job migration, the shifting of jobs from one country to another. At present, the U.S. economy is a net loser to such job migration. By contrast, countries such as China, India, and the Philippines are net gainers. And such countries aren’t just sources of unskilled labor anymore. They are now able to off er highly trained workers—engineers, scientists, accountants, health professionals—for as little as one-fi fth the cost of an equivalent U.S. worker.
