According to a BlackBusiness.org article dated July 25, 2016, "thousands of African Americans across the country are transferring their money to Black-owned banks that invest in urban communities and businesses." African Americans have a collective buyer power of over $1 trillion dollars, and the idea is to get this wealth to circulate through black businesses and ventures. This colossal transfer of wealth is called the #BankBlack Revolution.
This idea is the brain child of several celebrities, including singer, songwriter (and sister to Beyonce) Solange, and Atlanta rapper, hip hop recording artist, and activist, Killer Mike.
