American politicians had done little through the years to stem the flood. Hispanic voters wanted their kinsmen to be able to enter the United States regardless of their ability to contribute to the economy or pay their own bills, yet this wasn't the decisive factor. Farmers and small-business men wanted a source of cheap labor, and were content to pass the true costs, the social costs, on to the taxpayers. Generous public welfare programs also drew millions of Mexicans, more than small business or agriculture could possibly use. Even draining off an eighth of the population didn't really help Mexico, which found itself racked by turf wars between vicious criminal gangs that smuggled drugs into the United States to supply the richest narcotics market in the world.
