Who would that be, Mexico? Their greatest exports into the US to date continue to be drugs and illegal aliens. Simply transferring American wealth to these countries is doing little for them or us. If they're not capable of creating wealth on their own to begin with like Europe, Japan, South Korea, Taiwan and North America have then there's little we can do for them.
You don't know much about post WWII economic history, do you?
You seem to believe, like the Mercantilists, that the purpose of foreign trade is the enrichment of the nation, and this can be only be accomplished by a trade policy encouraging exports, which brings wealth in and discouraging imports, which wealth gold out. With all the hubris that is so typical of interventionists, the mercantilists presume to know what kinds of trade are good or bad and propose to regulate people accordingly. Even the most ardent paleoconservatives, other than Buchanan, have never been in favor of economic isolationism.
Trade does not require that someone lose. With free trade, both parties benefit. If they didn't, they wouldn't trade.
