The North American Free Trade Agreement (NAFTA) has caused many of these tribes to lose their lands, due to a government favoring the autonomy of Multinational Corporations. The Mexican Government is extremely Racist, as a full-blooded Native Person has never held any political power in the History of this country. Most Politicians are actually Pure-Bred Spaniards, who never take into account that 1/4 of the population of Mexico is Native American!
A large majority of the undocumented Farm Workers which we see working the fields through out the Southwest are from Oaxaca. Many of whom are ethnic Mixteco and speak ONLY this dialect! Many cannot Speak Spanish, and are seen as being ignorant and stupid by their fellow Latino counterparts! Most Mexicans don't realize that one of the most profound Revolutionaries of the country was a Oaxacan, the anarchist Ricardo Flores Magon!
Read a god damn Book motha Fucker! Don't let imperialism shape your mentality!"
