I'm sorry, I don't care how important they are to the U.S. economy, blah, blah, blah. If the price of lettuce goes up because employers have to hire citizens, big deal.
Until these illegal trespassers stop protesting in our streets waving Mexican flags, until they get it straight what country they are in, and if willing, begin the citizenship process, well, get the hell out (and no, I won't be vacationing in Mexico anytime soon).
Now as farf as German food goes.... hmmm... in the last twenty years America has become a food obsessed culture. Our food has gone from just so-so to exceptional, whether you're dining in San Francisco or New York, or chowing down on barbecue in Kansas City. Plus, our winemaking and brewing abilities have pretty much surpassed the rest of the world. I'm not talking jug wine and Budweiser either.
Do we take things from their original source and modify them? Sure, sometimes to the point of unrecognizability, but usually, to improve upon. We haven't been able to do much to Belgian chocolate, however.
