Amen. Its not so much about "immigration" - its that most Latinos who come to the USA are pickled in class-warfare rhetoric from their own societies and Gov'ts of their home countries. This doesn't disappear very quickly in the next generation either.
Mexico is one of the most racist societies you can imagine. Think about it. What do you see when you see Mexican politicians, or media personalities (including those amazingly hot women they sprinkle all over their news programs on Telemundo or Univision, not to mention the telenovela actresses)? They’re all pure Caucasian. They’re descended from the Spaniards that settled the country at various times.
Now look around at the (possible) illegals in your neighborhood hanging around outside Home Depot or slinging sod on a landscaping crew. They’re Indians. They’re descended from the native Indians of the country. The Spanish-descended Mexicans have never stopped treating the Indios like crap. They are Mexico’s permanent underclass, poorly-educated and low on the totem pole of society.
So it’s a huge win for the Mexican elites if we don’t solve illegal immigration by closing the border. They get to “encourage” their hard-working but uneducated and potentially troublesome lower class to head north. And then they become our problem, not Carlos Slim’s or Felipe Calderon’s.
It apparently doesn’t disappear quickly after five generations either. Those with out the education and otherwise to succeed on their own are unlikely to support an end to the government gravy train that they, their families, and their ethnicity are dependent upon.
