It helps both the U.S. and other countries - stronger economies, less unemployment, tighter bonds between countries and a better chance for peace in the world.
The idea of "exporting jobs" is a complete non-starter.
Read Paul Krugman of the NYT on comparative advantage, the basic economic theory developed by David Ricardo around 1805...
Ricardo's Difficult Idea"...And so one is prepared to be sympathetic after reading a passage like the following, on the first page of Sir James Goldsmith's The Trap: "The principal theoretician of free trade was David Ricardo, a British economist of the early nineteenth century. He believed in two interrelated concepts: specialization and comparative advantage. According to Ricardo, each nation should specialize in those activities in which it excels, so that it can have the greatest advantage relative to other countries. Thus, a nation should narrow its focus of activity, abandoning certain industries and developing those in which it has the largest comparative advantage. As a result, international trade would grow as nations export their surpluses and import the products that they no longer manufacture, efficiency and productivity would increase in line with economies of scale and prosperity would be enhanced. But these ideas are not valid in today's world." (Goldsmith 1994:1). On close reading, the passage seems a bit garbled; but maybe he is just a careless writer (or the translation from the original French is imperfect). One expects him to follow with a discussion of some of the valid reasons why one might want to qualify Ricardo's idea -- for example, by referring to the importance of external economies in a high-technology world.
But this expectation is utterly disappointed. What is different, according to Goldsmith, is that there are all these countries out there that pay wages that are much lower than those in the West -- and that, he claims, makes Ricardo's idea invalid. That's all there is to his argument; there is no hint of any more subtle content. In short, he offers us no more than the classic "pauper labor" fallacy, the fallacy that Ricardo dealt with when he first stated the idea, and which is a staple of even first-year courses in economics. In fact, one never teaches the Ricardian model without emphasizing precisely the way that model refutes the claim that competition from low-wage countries is necessarily a bad thing, that it shows how trade can be mutually beneficial regardless of differences in wage rates. The point is not that low-wage competition never poses a problem. Rather, what is significant is that despite ostentatiously citing Ricardo, Goldsmith completely misses one of the essential lessons of his argument.
One might argue that Goldsmith is a straw man, that he is an intellectual lightweight whom nobody would take seriously as a commentator on these issues. But The Trap is structured as a discussion with Yves Messarovitch, the economics editor of Le Figaro; Mr. Messarovitch certainly took Sir James seriously (never raising any objections to his version of international trade theory), and the book became a best-seller in France. In the United States, Goldsmith did not sell as many books, but his views were featured in intellectual magazines like New Perspectives Quarterly; he was invited to speak to the US Congress; and the Clinton Administration took his views seriously enough to send its chief economist, Laura Tyson, to debate him on television. In short, while Goldsmith's failure to understand the basic idea of comparative advantage may seem stunningly obvious to any trained economist, other intellectuals -- including editors and journalists who specialize on economic matters -- regarded his views as, at the very least, a valuable addition to the debate.http://web.mit.edu/krugman/www/ricardo.htmedit: typo
