A wise man once said that, if a nigger can't steal it, fuck it, smoke it, eat it, or shoot at it sideways, he'll wear it on his head. So sell status symbols they'll want to flash in public; and which they will kill each other for (note: it can be a sandwich).
If possible, invest in any business treating chronic illness amongst the black populace which they blame whitey for (diabetes, sickle cell anemia, bad breath, gunshot wounds, shaken baby syndrome, stinkfoot, drownings, cinnamon aspiration, believing they have to choose between weed or deodorant, herniated discs from morbid obesity, etc.) - It's a growth industry in which they're maiming themselves (and each other) in new ways every day, and it's never their fault. I bet some of them are out there right now, walking around without a head and waving at everybody.
