“Currently, a dollar circulates in Asian communities for a month, in Jewish communities approximately 20 days and white communities 17 days. How long does a dollar circulate in the black community? 6 hours!!! African American buying power is at 1.1 Trillion; and yet only 2 cents of every dollar an African American spends in this country goes to black owned businesses.”
