“We need to pool our resources” has been a recurring exhortation in the African American community for decades. For example, here’s Dr. Martin Luther King in a 1958 interview:

Question: Do you think Negroes are partly responsible for their plight? They don’t stick together and they don’t help each other. Negroes, for example, will walk past a Negro-owned grocery store or shoe shop to get to a white place. Instead of trying to make themselves financially independent, most Negroes are trying to keep up with the Joneses. Isn’t it time for us to stop begging and stand on our own feet? 

Dr. King: I quite agree that there is a great deal that the Negro can do to lift himself by his own bootstraps. Well has it been said by one that Negroes too often buy what they want and beg for what they need. Negroes must learn to practice systematic saving. They must also pool their economic resources through various cooperative enterprises. Such agencies as credit unions, savings and loan associations, and finance companies are needed in every Negro community. All of these are things that would serve to lift the economic level of the Negro which would in turn give him greater purchasing power. This increased purchasing power will inevitably make for better housing, better health standards, and for better educational standards.
