Ross is dropping jewels throughout the album if you actually listen. On the intro you have the "mastermind" self-help audio playing. This is a hint to the mental development that took Ross years to complete. "you can borrow other peoples knowledge, achievements, life experiences, and even their personal resources in order to execute your own life goals." Ross understands despite what people say, they still want to hear drug dealing, cars, women, and money in their music. Why should he reinvent the wheel? Create a character based loosely on a real street dude and go over the top. At the same time, make enjoyable music because at the end of the day that is all that matters.
The Diddy rant on Nobody is another example. People hanging around bums and wondering why their life doesn't get better. No one is ever going to give you shyt in life for free. You have to go out there and take it. That requires going into the "dark" as Diddy says where you don't know what the outcome is going to be. However, people would rather play the safe role and not do anything talking trash from the sidelines.
Ross is so comfortable on his tracks that his "story" doesn't matter. 99% of rappers have hyped up their past. Take Jadakiss for example. In the "Oil Money Gang" video, Ross is moving all over the place just messing around while kiss is stiff as a board still trying to act tough. Ross is a master salesman who happens to make good music.
