“Ricardo’s other necessary condition for comparative advantage is that a country’s capital seeks its comparative advantage in its home country and does not seek more productive use abroad. Ricardo confronts the possibility that English capital might migrate to Portugal to take advantage of the lower costs of production, thus leaving the English workforce unemployed, or employed in less productive ways. He is able to dismiss this undermining of comparative advantage because of “the difficulty with which capital moves from one country to another” and because capital is insecure “when not under the immediate control of its owner.” This insecurity, “fancied or real,” together “with the natural disinclination which every man has to quit the country of his birth and connections, and entrust himself, with all his habits fixed, to a strange government and new laws, check the emigration of capital. These feelings, which I should be sorry to see weakened, induce most men of property to be satisfied with a low rate of profits in their own country, rather than seek a more advantageous employment for their wealth in foreign lands.”   Today, these feelings have been weakened. Men of property have been replaced by corporations. Once the large excess supplies of Asian labor were available to American corporations, once Congress limited the tax deductibility of CEO pay that was not “performance related,” once Wall Street pressured corporations for higher shareholder returns, once Wal-Mart ordered its suppliers to meet “the Chinese price,” once hostile takeovers could be justified as improving shareholder returns by offshoring production, capital and jobs departed the country.   Capital has become as mobile as traded goods.”
