That's true --- the society pages in Mexican newspapers also show a lot of of non-Spanish last names. The irony in Mexico --- the elite class consists of mostly Europeans who are running the Mexican people out of their own country while they themselves raid it of all it's wealth. The indigenous Mexican is not entitled any access to the vast wealth of Mexico -- not even if they are willing to work hard.
Sadly, it is typical of Latin America. It has been like that since the first Spaniards set foot in the New World.
