Even in our community, the black kids speak differently than the white/Asian/Hispanic kids...what is going on culturally with this particular group that they can't/won't talk like everyone else?

I can't imagine it's a physical/mechanical issue with mouth structure, I have to assume it's a learned behavior. What does a black person stand to gain by using a dialect that is unintelligible to the rest of society? How do they expect to accomplish anything if they can't even express themselves verbally?
