I'd consider a rapper "smart" only if they saw past the industry. Once a rappers hits it big, they start buying houses, cars, jewelry, etc. That shit's not important in life. If you really had your shit together, you'd try to influence the masses in a positive way. You'd stop misleading the masses by not rambling on about the "bitches," "weed," "ice," cars, and how much shit you got.
People with power need to stop taking it for granted and start doing positive things for the people.
