what's up with bling?

who benefits when rappers and athletes buy bling. sure they may look cool to some, but where does the money trail go? does it enrich the community they came from? do they get it mail order direct from africa to support them? does it go to a bunch of rich white guys who own the rights to the minerals and then have it made in a third world country so they can get it made for just a few cents, and then sell it to them for a HUGE markup?

snoop once talked about a snoop-mart. how's that coming? with all the money these athletes and rappers are making you would think they could invest it in their community and turn their riches into wealth.
