Nah, the concept is there, but Blacks go out their way to give whites their money in order to feel they "made it". And then we also create the negative stigma that all black businesses are janky, and black folks "dont know how to act". People will quote Malcolm when he speaks on self defense (even then they are too scared to do that), but never quote Malcolm when he talked economics, same with MLK.
Blacks globally will never have respect until we develop an Economic Base and Infrastructure. We think giving others our money = respect, and we look like fools. heck we have Africa, the most resource rich land on earth, but we can't even do anything with the resources because we lack infrastructure so outsiders come in and build infrastructure but at a cost that does more harm than good.
