what difference does that make. Mexicans are historic enemies of the United States, and notoriously corrupt (Mexicans themselves will tell you this). They are taught from the elementary school to hate us. Why import enemy separatists? I'd prefer bringing in grateful, honest, friendly, non-separatist immigrants to do the work that needs to be done. Like Poles, Indians, Chileans, etc.
If Mexico wants to be a socialist paradise, let them do it, give the people a land reform so they can have their huts, grow corn, and subsist. This is the walk and talk of the present-day Mexican politician, but when it comes down to providing the people with what they need, they are almost completely dependent on us - and I think most Americans are sick and tired of their act. We are rewarding these pathetic oligarchs with immigration reform, too. What did they do to deserve it?
