"Does the writer actually think the people are running from Mexico for the opportunities here, and want to use those opportunities to turn THIS country back into Mexico ? "
No, I don't think that is what he is trying to get across. It is not the individual illegal alien that wants to turn the Southwest into Mexico, it is the Mexican Govt. using the illegals to do this. The individual illegal is a pawn in his dangerous game. Those in power in Mexico need the money that is sent back by illegals, so they may remain in power. Corruption is rampant and so deeply embedded in Mexican Govt that it affects their economy. Without the money that comes in from illegals Mexico's economy would crumble faster than you can say taco. I believe the Mexican Govt has no other choice than to push it's people to migrate north, they can't provide an economy that will sustain their population, and in pushing migration, they may accomplish their goal of "Reconquista".

By your own reasoning, they would be killing the goose that lays them the golden eggs. People in their OWN economy can't generate those funds, and they know it.
