If I were to say "Bob Geldof" to you, what would you think of?

Chances are you'd say "Live Aid", or if you're younger "Live 8".

If I were to say "Usher" to you, or "Nelly" or "Fifty Cent", what would you think of?

Again, chances are you'd say "rap" or "hip hop" or "bling".

Bob Geldof, a white man, a non-African American has raised millions of dollars to help African people living in poverty.  He's drawn the world's attention to the horrors that happen on a daily basis in Africa.

Usher, Nelly et al, black men, African Americans have done....not a lot. 

Why is that?  Why is it the black Americans, or African Americans as they like to be called....why is it that they've done little to nothing to raise money to assist the people living in the country they claim such an affinity with?  Why haven't they used their superstardom as a platform to draw attention to this cause? 

Why is that?
