You guys ever listen to rock music? What they sing about is a completely different lifestyle.
I think hiphops story of a drug dealer getting rich is getting old. But trap music, loud and bashful gets more attention than lyrical, cerebral stuff.
But to each culture this is normal. Music is an extension of the lifestyle these people live. We give it up to our worse because its a good story to see the bottom go to the top. But there is no purification in the process with most hip hop artists.
It comes down to nature vs nurture, and we have been groomed to become this.
