Bitch please, there is NO WAY your networth is more than someones and then you make more money then them for several years and your net worth is suddenly less. YOU mentioned Diddy's networth and said it was the first time and years Diddy's networth was more than Jay's in a Jay Jay made more money. So, get your shit straight really. The only way you can be right is if Jay lost a bunch of money and Forbes isn't counting it, which I doubt.
EDIT:
It's like this, If Diddy has 80 million and Jay has 81 million and Jay Earns 10 million a year for 10 years while Diddy earns 5 at the end of the day their is no way Diddy passes Jay. Now if Diddy is Richer than Jay to start then Jay can make more and not catch diddy that's the only way it can be done so if Jay is making more Yearly and Diddy is still worth more the only way Diddy is still worth more is it he WAS ALREADY WORTH MORE.
