common and teachers have never done anything about it. The Number one and two reasons for bullying are skin color and at least perceived economic status. Kids with darker skin here get bullied by those even a shade lighter, most in the us probably could probably not tell the difference. This is indigenous looking kids (like my skin color) bullying slightly darker kids mercilessly. It's considered a class thing FAR worse than anything that happens in the US, one reason you rarely hear new immigrants call racism there. Most in the US do not know that. Economic is a part of that, but skin color more. Most there would probably scratch their heads to see dark skinned kids bullying those slightly darker.
My wife was bullied for it in school, the 18 year old daughter is bullied over very dark skin, I know a girl neighbor (17 or 18) that is very pretty but bullied big time. The teachers will not listen, do not care and nobody cares as it is accepted. I did see a woman go to school and outside on the street flattened a girl for bullying her daughter over slightly darker skin.
In hiring practices you can specify sex or age of who you are looking for. Most want women between 18 and 30 and fire them around 35. It happened to my sister in law that worked as an executive secretary in Mexico city. At 35 she was fired for a younger person, now she works packaging cooking pans for minimum wage. Less than 70 pesos a day at least 10 hrs a day.
So the point is that discrimination is rampant at the top so pena nieto is just blowing smoke.
They are also lying, nobody is shocked.
