Where do you all get the idea that there are five rich rappers? Have you ever seen MTV Cribs? Come on, now.. Jay-Z, Puffy, LL are SUPER rich rappers, but that doesnt mean others dont have shitloads of money.
And what musicians do you know that actually get an education. I would say about none of them. Would you get an education if you got paid millions to do what you love, party all the time, and have a fantasy life. I seriously fucking doubt it. Just because you dont like hip hop, you dont have to clown rappers.
