Did you know that? George Grayson, professor in the Government Department of the College of William and Mary, writes about this phenomenon.

Mexico has beaches, luxury resorts, archaeological treasures, museums, gold, silver, oil, natural gas, copper, coal, fisheries, specialty fruits and vegetables. The only reason our southern neighbor has so many poor is that it operates on a feudal system in which the upper classes keep the wealth to themselves rather than creating an economy which allows prosperity to spread. So they send their poor to the U.S. to work at wages below what Americans need in order to be able to live like mature adults instead of like a bunch of frat boys renting a house together. This enables Mexico’s upper classes to continue to enjoy their wealth and enlists us in supporting their oligarchy.
