I really wouldn't want to live in America. I found New York claustrophobic and dirty. I missed England when I was there simple things like smells and the British sense of humor.
I would argue that we have a generation of young people particularly minorities who are no longer putting up with the kinds of things their parents put up with. They're much more self-confident. It's no longer acceptable to make fun of people because of race or sex. But it has always been present in American society.
