Is the U.S. still racist with Immigrants?

Why can't they have a normal life in the United States? They are normal people, just like you and I. Many people just like this family cross the border of Mexico everyday, looking for a better life.It makes me sad to know that many of these immigrants are treated unfairly because they simply aren't American citizens. I understand the Americans because it is their country and they want the best for it, but they also have to understand that not all of these immigrants move to the U.S. for drug trafficking or other bad things. The majority of the illegal immigrants are in the U.S. wanting to have the American desire and being able to have a job and be successful in their lives. Having protection in the borders of the U.S. is good because it avoid many conflicts, but it is very aggressive when non-citizen people, looking for better opportunities, try to cross. Immigrants move to other countries to have a better life, not to make it worst.
