The presidential campaign seems to have time-traveled back to 1992, when independent candidate Ross Perot thought he heard the "giant sucking sound" of American jobs moving to Mexico.
Perot lost his presidential bid, along with the argument against globalization. The winner, Bill Clinton, went on to sign the North American Free Trade Agreement. The resulting U.S. job losses, primarily in manufacturing, were offset by gains elsewhere, according to numerous studies.
Two decades of bipartisan support for globalization should have settled the matter as a political issue. Instead, President Obama reopened the debate with television ads attacking Mitt Romney's tenure at Bain Capital, saying that Bain invested in companies that shipped work to overseas call centers and factories.
The president hopes voters will conclude Romney isn't the job creator he claims to be -- even though FactCheck.org, a nonprofit group, found no evidence to support the charge that Romney, while still running Bain Capital, sent jobs overseas.
Romney responded with equally specious claims alleging that millions of stimulus dollars were diverted offshore, making Obama the real "outsourcer-in-chief." Most of the claims, however, are a mishmash of exaggeration and falsehood.
The reasons for the charges and countercharges are obvious. Victory in November will require winning some combination of swing states such as Michigan, North Carolina, Ohio and Pennsylvania, where the outsourcing allegations hit home with millions of workers who can no longer rely on comfortable paychecks or even stable employment.
Yet despite the cheap shot from Obama, and a foolish retort from the Romney camp, perhaps this is a debate worth having. Is it possible for the United States to engage in globalization without offshoring jobs? Are the benefits of globalization still worth the costs?
Virtually all U.S. companies and consumers have benefited from the lower cost of clothing, cars and computers made overseas. At the same time, hundreds of millions of people in emerging markets -- more than the entire population of the United States -- have climbed out of poverty because of the free flow of goods and services across borders.
