A rapper does a few hours work, it buys him a new car. Very rational cost-benefit, even if short-sighted. It'd seem exceptionally inefficient for that rapper to launch a political career for the purpose of increasing his fortune, particularly with the increased scrutiny and fewer post-term consulting gigs he'd have compared to your average politician. I can see celebrities doing it for the fame though-- specifically to show that they're "more than" an actor, singer, athlete, or whatever.
