The reason African-American aren't opening shops in their own neighborhood is simple: African-Americans are comsumers not producers. Many of us would rather spend our leftover money (money after paying bills), buying EXPENSIVE, name brand clothes, shoes, cologne, jewlery, ect. instead of saving it. African-Americans have the resources to have their own (we ARE the top spending race), African-Americans just don't (in many cases) have the entrepreneual (sp?) spirit or desire to follow through with the dream.
FYI: Of course the business owners don't care how they treat their customers; many times the customers don't have any choice and will continue to patronize the offending store. That is why prices are so inflated in certain neighborhoods.
