Michael Savage once posed the question that regarding celebrities, has there ever been a time in history when the compensation was so disporportionately inverse to the ability.
Think about it. Spears is a singer, and not very talented at that. Lohan is an actress, and limited in her abilties as well. As for Hilton, she's famous for being on magazine covers without having merited it for achievements of ANY kind.
I think hilton's fame is in being the rich slut that all of the men who were ever rejected would love to pay back.
