Mexico's ruling class, (also its productive classâ€"there's a reason they're on top) is composed of mostly white people descended from the Conquistadors, and and people of immigrant stock like Carlos Sarukhan, the Mexican-Armenian ambassador to the United States.
I believe the last President of Mexico who wasn't white was Lazaro Cardenas, a radical who nationalized the oil companies, ensuring that oil exploration in Mexico would be done by the Mexican government. (Yes, they are running out of oil.)
