Sorry, but you need to research more about the children illegally brought here by their families. The majority of them “ARE SKILLED”! Talk to a few and you will learn that most had jobs in Mexico like dentists, nursing, etc. One story: a Mexican dentist who close his office in Mexico due to the poor dentist salary & also people were to poor to go to the dentist. The majority gets a degree and are fighting for a higher education denied because of the illegal status.
Also, you do not address why Mexicans make more than African Americans. Mexicans are hard workers and are dedicated to taking care of their families. Those jobs they “supposedly is taken” most African Americans don’t want to do. Personally, from association I see this. They come here with a dream to succeed in America. The majority of the families have income from both parents. This goes for illegal Asian immigrants also. I’m guessing that African Americans has lost that zeal that these illegals have for the American dream.
