cant vouch for the accuracy of the stats but check this out....
"The race begins. Who will be the first to earn that next $700 million? Will it be Sean Combs with his fashion, record label, music publishing, music production, restaurants, marketing, and talent management empire? Or, will Percy Miller's fashion, sports management, film, record label, music publishing, retail, and real estate empire catapult him to the top ranks? Both entrepreneurs are reportedly worth approximately $300 million, according to Fortune Magazine.
Amazingly, Percy Miller (pka Master P) who first made the list in 1999, topping Michael Jordan's estimated net worth of $358 million with a jaw dropping fortune of $361 million, made number 20 on the list a second time in 2001, with an estimated net worth of $250 million, and a third time this year, cha-chinging in at number 11 with an estimated net worth of $294 million. Sean (P Diddy) Combs made his debut to this elite club last year at number 22, reportedly worth approximately $231 million. Who in the Bronx nearly 30 years ago could have imagined that, in 2002, three hip-hop artists (Will Smith also made this year's list with a net worth of $113 million) would be on the list of the Forty Richest Americans Under forty?"
