Mainstream America has some fascination with watching how people in higher status live, hence successful reality TV. It's not hard to understand, it happens world wide, with people of power such as sports stars, rulers/leaders, and others of high influence.

I don't really care how Nick & Jessica spend the day or how some high schoolers get ready for prom, hell I don't even care about somebody's dream of becoming an American Idol. But shit sells to others so what can you do?
