Riiiiight. Hey Mexico, you put a STOP to the illegal immigration AND illegal drugs coming into the US over the border, and then we'll see about tightening up the flow of weapons to YOUR country.
How can Mexico stop depending on exporting poverty unless it begins to allow its people to create wealth for themselves? In other words Mexico would have to change its government more than it has been able to do. Maybe if we took away our oil dependence it would give them some incentive to have to allow entrepreneurship along with some other folks that need the same solution on our part to stop harming us.
