If Mexican (in particular) labor was able to come to the U.S. to work a lot of people might be surprised to learn that they'd go home when they could. Most people have a fondness for the place where they grew up and they want to stay there. Given the best of both worlds, many who are illegal today would come and go happily and legally if they were given the opportunity. And when you read about not just the horrors of getting across the border but also of the horrific trip up the length of Mexico, those coming to work here would be better served to save their money for a ticket to ride IN the train (and not on top or on an undercarriage) and walk or ride across, not pay a coyote to direct them to swim or hike, or die.
