Mexico is a racist state. White-Europeans control virtually all the wealth in Mexico. It's no wonder they want to foist their "untermenschen" on the US.
James Michener wrote "Texas" and "Mexico," and both books describe the history of Mexico.
He described the status ranking, by race as it was in the colonial days.
--Highest status=born in Spain
--Next highest=born in Mexico to two Spanish parents
--Next Mestizo or part Spanish, part Native Indian
--Lowest is Native (like an American Indian)
Articles not long ago, mention that virtually the entire entertainment industry seen on Mexican television, is mostly European ancestral mix; eg. few with very much Native blood.
