This is hyperbolic and boderline bigoted. First, Mexicans face extreme violence form Mexicans, not Americans. They flee to America largely to avoid that, and to have some hope of prosperity, which is afforded to them by the millions. Second, responsible border control is a foundation of stability when disparate nations share a border. Open borders between a state which is to some extent run by hyper violent cartels, and where there is a normal civil situation on the other, is only going to lead to disaster. Finally, there really should be border controls going in the other direction as well. In the US->Mexico direction, there's nary any control. There are all sorts of ways to facilitate a proper customs union, keep traffic moving, and make sure everything is in order - it just takes a bit of political will.
