I would argue it's very unclear if it is in the best interest of everyone else. Immigrants send money home (out of our economy). Companies may produce more/cheaper, resulting in possibly lower prices. But maybe they just spend the extra revenue lobbying Congress for preferential treatment. Maybe it results in more money shipped offshore to tax havens. And if indeed immigrants are just cheaper replacements for their American counterparts, it takes away money (which, remember, is equivalent to speech) from citizens of this country.
