Of course Mexico buys grains, some consumer items (El Nuevo Tide) and some industrials from us but the point is we run a trade deficit with them. Not that you care
Wow. People that read the above might fail to realize that Mexico is the third largest U.S. export market, and that the vast majority of U.S. goods exports to Mexico are manufacturing/high tech/capital goods. As for your point, as always, when you utter such inanities as "[w]hat American crap are the Mexicans buying?" you are never speaking of the trade deficit, you simply change the subject to the deficit when I call you on it.
Moreover, the irony of you appearing on a thread that concerns a Mexican customs facility (customs facilities are primarily constructed to handle imports, i.e. U.S. exports to Mexico) is delicious.
