Americans also have their roots. They bring their own cultures, religions, customs, ideas, and manners of doing things and the like. And they make them prosperous. The United States is a nation created by immigrants, and immigrants continue to affect the nation greatly. It forms a unique culture. By the reason of the rootlessness of American people, many kinds of different cultures coexist at the same time in the United States.
