Most minority groups have historically "supported their own" in some way in this country.
There were thriving black communities in this country in the early and mid-20th century. Think of Harlem or the South Side of Chicago. Black-owned businesses were everywhere. Education was valued. Blacks were shut out of white communities and white businesses and they made their own. You had black teachers, professors, lawyers, doctors, bankers, policemen, etc. etc. You had a real community.
What happened?
FORCED integration happened. As we are all aware, government intervention causes problems and this case was no different. Govt intervention destroyed black communities, destroyed black businesses.
For decades, blacks have tried to figure out where it all went wrong. I have had the opportunity to work on two oral histories of blacks as a transcriber. I have listened to numerous interviews of blacks who lived in these thriving communities and can't figure out why the black community has imploded in recent decades. They blame drugs, they blame lack of education, they blame poor family structure. But they DON'T blame government. And they should because govt is the primary cause.
If this all seems tangential, I assure you it isn't. It is this mindset that brings about this "buy black" mentality. The proponents clearly have knowledge of the successes of the past, but don't understand why it all fell apart. They are trying to rebuild the black communities of the past. What they are missing is the need to break down the govt if they really want to reclaim their history.
