Mexico's race problem

When Trump stood on the stage with President Nieto of Mexico, I couldn't help but notice that Trump was darker than the Mexican president. But maybe it was the make-up for the camera. The ruling and wealthy classes of Mexico are very fair skinned, as are the TV celebrities and movie stars, at least the ones I see on American owned Spanish language TV like Telemundo and Univision. There are some strict rules for Mexico's naturalized citizens quite different from ours and many government elective offices are closed to them. You can shorten the residency requirement for citizenship if you are a native born Spaniard, which would of course make you lighter skinned than someone entering from Central America. or the islands or Africa. But the only people crossing the border into the U.S. looking for better lives or temporary jobs to send money home are brown. The gangs bringing in the drugs, too. Why are Mexican leaders exporting their brown citizens? Mexico is a very wealthy country in natural resources.  Who is the racist here?
