Does the American Dream really exist?

It does exist for many Americans, but it certainly not for all Americans or immigrants. It is known that the American authorities have been doing anything to give the same opportunities to all Americans, but these efforts are not enough. We still see racism against black people. As evidence, we can find neighbords where just black people live or acts of violence against them; black people and immigrants live in poverty in the city while most white people live in the suburbs, far from the city. Even though many immigrants are really succesfull in the U.S.A., others are forced to take any job because they are undocumented.

This issue will still be discussed as long as American authorities do not create effective laws that allow immigrants to really have equal opportunities. It is going to be very difficult to achieve real freedom and equality in the U.S.A. One reason could be the mixture of cultures having to live together in the same country. Perhaps it is hard to deal with people coming from very distinct cultures; however that's not reason to discriminate anyone. What do you think?
