LOL ... really, you wonder why their people would leave such a rich nation to come north, check their tax rate, it is only 12%! This is how trickle down economics really works, 10 of the 26 billionaires in Latin America are from Mexico. They didn't become that way by giving away their money in taxes to help their unwashed multitudes nor has their low tax rate meant more investment in jobs for Mexicans ... in Mexico!
This is what Romney and the republicons have in mind here, cut taxes down to 13%, get rid of all of the safety nets and you won't have to worry about illegal immigration anymore. It will instead be your chidren looking to emigrate as they seek for a better life ... perhaps sneaking into Canada, Australia?
