Whose jobs will they take at lower wages? Zip, if we're talking about undocumented immigrants. Or are Americans lining up to pick produce, clean hotel rooms and work in processed meat plants? As for legal immigration? Immigration law could be targeted to retain foreign students who graduate with STEM skills. Why send the Chinese math wiz or the Indian software genius back because their student visa expired? I mean if Red State America can't produce enough of that kind of talent, why should the rest of us pay. We already pay too high a price as a country for willful ignorance, xenophobia, scientific illiteracy and racial bigotry.
