I saw Surrogates today, it was really good. Basically, this guy invents "surrogates", very human like robots controlled remotely by a neural interface. Almost the entire world gets them, and people start living through their surrogates, who suffer no illness and are always in perfect health. There are the people who refuse to use surrogates at all, and are basically treated like Native Americans (IE: they live on sovereign reservations around the US [I guess the world too]).
