There was a story, that unfortunately I only heard about secondhand.
The premise is that there's some future society where, due to globalization, eventually all races became homogeneous. Somehow, there was a white guy from today that was born or time-traveled or something so that he's a part of this society. Except . . . the people of this society want the white guy to not feel different.
So, ever since he was very young, they build a world around him that he grows up in--some kind of enormous stage. And they get actors to pretend to be his mother and father and people in his village (the actors all wear makeup so as to appear racially diverse). There's nothing else really to do except make a TV show about it--so this white guy becomes the subject of a reality TV show.
One day he gets a little suspicious and starts heading off in a given direction, but the people just start building the world ahead of him, so that he never leaves.
