I was going to say EXACTLY what you just said. This movement needs someone like an MLK or a Malcom X. Someone who is fairly young, but not too young, but experienced enough in decades of inequality to see everything from all sides.
Sadly, it isn't here. Tupac would have been that guy. He would be around 50 right now, and it is very safe to assume that had he followed the path that he was following in regards to inequality and injustice, he would have been right on the front lines. I think that was his higher calling once his rap career was done. He wouldn't have been somebody to throw money at the problem.

Anyone that actually listened to the man, knows that he was as multi-faceted as you can get, without sacrificing his roots. My wife was surprised at the level of articulate conversation that he had in a LOT of his interviews.
I told way back then he was much much deeper than what you saw on the surface
