i think it has to do with hotness at the moment as well...
because angelina jolie raked in about 20 million and she is higher than jerry bruckheimer who is at #39 with 120 million. so i don't think its money that is the sole factor or the biggest factor apparently. i would imagine mariah has made probably close to $20 million with different things she was involved in. the advertisements with pepsi, the tour, the royalties. stuff of that nature.
