Who's to say that Nas has even been putting the same amount of effort into growing his money? These random comparisons are stupid as fuck. First, Nas hasn't even made as much money from music itself as Jay, so that comparison is already flawed. Second, how do you know Nas was even putting the same effort into growing his money as Jay? So because Nas may have been content to just chill and make a few light investments rather than chasing a billion like Jay, that means Jay is a great businessman? Don't ever call someone else's logic dumb, when yours rests on straight stupidity.
Other people being shitty businessmen or more easily satisfied with lesser riches does not mean Jay is a business genius. Again, I'm not saying Jay isn't a good businessman. I'm saying there is a difference between going from nothing to a billion based on business acumen and going from nothing to hundreds of millions because you're an extremely popular rapper and then using those millions to get to a billion. The way our system is set up, having lots of money makes it much easier to make more money. That's just a fact. Let you niggas tell it, Kylie Jenner is a business genius too cause she's a billionaire? I guess she's better than Jay too since she did it faster huh?
