Oh, the Mexicans that are fleeing their country can find jobs in Mexico, if they are willing to live at somewhat lower level than a freed slave turned sharecropper in Mississippi in 1920.
There is an intense internal racial prejudice within Mexico, in which the descendents of the "hildago" class, the most European of the Mexicans, have always retained their position as the (mostly) unelected ruling clique, while the indentured servant class, the "mixed" Mexicans, and relatively unintegrated Indians have always been the underclass. The ruling clique has title to most of the land in Mexico, and have maintained a legal system that preserved the status quo since about the time the Hapsburgs were kicked out of Mexico. There have been various peasant revolutions, but always, the ruling clique eventually reasserts control.
Time for the US to invade Mexico and give them at least as modern a constitution as has been drawn up in Iraq. Or maybe the US could simply annex the entire country and give all Mexicans the same status as Puerto Ricans.
I had a poli sci professor whose specialty was coups de etat in Latin American countries. He mentioned there have been hundreds. He also said that the US Constitution has been tried there many times, and has always failed. The reason: culture. They don't think of government as subject to man; they don't revere their institutions (except their militaries, which have stepped in time and again to rescue them from despots.) Our Protestant heritage is what separates us. Samuel Huntington develops the argument very well in "Who Are We." Excellent read.
Interesting fact in light of the author's observations.
I also have often thought the only answer to Mexico's problems is annexation or at least a new constitution---something to create private property rights. Not only is the lack of private property rights a barrier to a functioning economy, it's a barrier to foreign investment.
