"For many years, Mexico’s leaders have been taking advantage of the United States by using illegal immigration to export the crime and poverty in their own country (as well as in other Latin American countries). They have even published pamphlets on how to illegally immigrate to the United States. The costs for the United States have been extraordinary: U.S. taxpayers have been asked to pick up hundreds of billions in healthcare costs, housing costs, education costs, welfare costs, etc. Indeed, the annual cost of free tax credits alone paid to illegal immigrants quadrupled to $4.2 billion in 2011. The effects on jobseekers have also been disastrous, and black Americans have been particularly harmed."
