The rich and powerful in Mexico are mainly white Europeans. It is the under class, Indios and Mestizos, who come to El Norte. The ruling class in Mexico is ok with that. The Mexican Nationals in the US also help pay for the underclass that remains in Mexico through remissions. If the Current status quo changes and millions of poor and uneducated Mexican nationals return to their mother country there could be much social unrest. Viva Zapata.
I was just at the pool and lakeside restaurant (here in Mexico, where we live in a resort community) and the kids had blond hair from their light haired, light skinned parents, and they are what many Mexicans look like that we encounter in our neighborhood.
Yep!
It is a classist society, much like India, I believe.
