Where did you read this information from? There's many inaccuracies and possibly misinformation.

The Black Disciples have an estimated 4,000 members in Chicago metro depending on the source. BDs leaders earns a various amount of money depending on their location and there's no 20 member board of directors.

Each deck (crew) range in size of 20-50 members, and they're involved in gambling, extortion, gun trafficking, other crimes as well.

Therefore if your going to compare the Outfit to the BDs then you chose a specific deck and not the entire collective. If you regard power to numbers or activities. Most of your mobs in Chicago have legit businesses and involved in other rackets just like the Outfit. Many people don't realized this due to lack of interest.
