We are talking about two different things.
You are talking about crime organizations that are based on being a certain ethnicity and all their crime activities are to the upliftment of those people. That takes generations and is difficult to accomplish.
That's not what Avon, Stringer and Marlo were doing. They are selling drugs in their own community to their own ethnic group to enrich themselves. They and the commission Stringer set up are not in it for the long haul to 'go legitimate'. They were short sighted and didn't come at it from that angle, all they wanted was to cake off individually and keep the cops out of there business. No individual can play it like you are suggesting and make it to the end of the game that way, it takes a group that is dedicated to it generation after generation.
That's some 'I know all I know about organized crime from TV' type perspective. That's what the Godfather wants you to think. IRL them Italian and Irish mobsters were no different than cats like Avon, they just were more structured. They literally terrorized their communities which is what protection rackets were about. They weren't uplifting their 'people', just their own pockets and would steal from each other and kill each other whenever necessary. Don't fall for that lie that these guys were somehow 'honorable' or white collar. They were thugs in every sense of the word but they had structure. They, as much as anyone insured that black organizations didn't have that structure because they were a threat.
