because thats what sells albums today. if you took out all of the lyrics in hip hop in reference to cars, rims, ice, chains, drugs, women, and sex, we would be left with just beats. hip hop was created to speak about the hardships of growin up, and the references to all of the material items and fame are just ways to forget about all of it and move on up.
not too many white rappers fit that bill, and if they do, they dont have the balls to be a rapper, or their managers, label, etc., dont have the balls to promote them in this industry. thats how it is at least up until today.who knows, maybe it will change. it already has a little, look at kanye, he grew up middle class, good neighborhood, good parents, good school. far from what hip hop was and is, and he's one of the most dominating voices in hip hop for the past few years. maybe a white producer will start spittin and be the next kanye. you never know.
you just gotta be different, and hope it works, but i dont think the public is ready for a white kanye or whatever at this time
