I believe that this image perfectly demonstrates the variety of cultures and nationalities in America, as it shows each county's most dominant ancestry. People from all over the world have looked for settlement there and as a result, this has made America an incredibly multicultural nation. It proves how rich America is with opportunities and a better life for many, because if this wasn't the case, we wouldn't see the range of nationalities that we see in this image. It too, justifies the assumption made by many Americans, that their country is the epicentre of the world, as so many foreign citizens have wanted to travel and live there. Although it's mainly dominated by German, Mexican, American and African descendants, it would be tough to argue that we would see this much variety in any other country.
