Quoted from "The New Global Job Shift":
"If foreign countries specialize in high-skilled areas where we have an advantage, we could be worse off," says Harvard University economist Robert Z. Lawrence, a prominent free- trade advocate. "I still have faith that globalization will make us better off, but it's no more than faith."
If the worries prove valid, that could reshape the globalization debate. Until now, the adverse impact of free trade has been confined largely to blue-collar workers. But if more politically powerful middle-class Americans take a hit as white-collar jobs move offshore, opposition to free trade could broaden.
