Back from the turn of the 20th Century to about the early 1940s, generally voluntary segregation in the US could be seen in many small towns, with there being a black part of town.
Importantly, while there was a town government, there was also a “pecking order”, representing a “shadow government” in the black part of town. Often the leader of this shadow government was the undertaker, who was often the wealthiest and most respectable black leader. Number two would likely be the most popular reverend.
As such, the undertaker and his clique of the wealthier blacks would have direct dealings with the white elected town officials, acting as liaisons to the black community, which functioned to some extent to let the white leaders know if there were problems in the black area, be they infrastructure or social.
Not all blacks were equal. Local residents all knew each other, and word got around if a transient black of low character had arrived in the black part of town. He would be encouraged to leave. Respectable new arrivals would be welcomed and accepted as usual.
However, with the onset of the Great Depression and World War II, this segregation quickly broke down outside of the deep South. The end of the war with grand demographic shifts from rural to urban living erased it from most of the US. That it survived into the 1960s in the deep South was an increasingly uncomfortable anomaly.
I mention all of this as background to how a black community organization can work. The author has the first part down right, but it must be eventually associated with a “better business” rating, if it is to succeed in the long run.
That is, just because it is black run does not mean that it is better, either in comparison to white run businesses, or to other black run businesses. It must swim or sink on its own merits, the quality of the goods and services it provides.
If it is a good business, honest and fair, and sells a good product or service, it deserves the extra support of the black community if they like it, and are willing to support it. But if it isn’t, just being black run isn’t enough.
Money’s green. The only way segregation can be or ever has been enforced is by government.
