What good is it being in the upper class if there is such a big middle class that people are not willing to do whatever you say just to survive. Mexico has a wealthy class who are very very rich and a whole lot of poverty. By maintaining a totally corrupt government those who are in the super rich class are not really subject to the laws like the campesinos. This is very good if one is in the super rich class. Unfortunately the USA is moving towards the same economic structure with similar corruption.
Welcome to Feudal 14th Century Mexico. I believe Mexico has 4 of the 12 or 13 Latin American billionaires. Most of them come from the same group of families. They could devolve some of their wealth to the "little people" (actually, they refer to them as "cockroaches", but hey, this is a clean forum, right?), but their contempt for their countrymen runs so deep that they would never consider it.
Since the gringos have shown themselves to be "weak" by employing Los Campesinos, and providing them with welfare and free schooling, the Mexican Caudillos are thrilled to exploit this weakness. And exploiting weaklings is what they have excelled at doing for 500 years.
What's really hilarious to watch is the current administration bending over for this crap. One sure way to encourage the Spaniard thugs of Mexico: roll over for them. Mr. Bush recently decided that he needed to go 9000 miles away to show he means business. He could also put up a fight on the U.S. border, and that would be the slap in the face that would tell these Conquistadore terrorists that the game was over, and the U.S. wasn't playing anymore.
They aren't our "friends", they aren't culturally "related" to us, and they don't believe in the same things AT ALL, and people who believe that are deluded, and open to cynical exploitation by these a**holes.
