I think we got way off topic here however, LCN used to supply the pimps/hustlers etc. in the minority neighborhoods going back to Prohibition, LCN would also act as a bank for numbers, in a lot neighborhoods, after prohibition then it was Cocaine, Heroin and than Crack.

At some point when American LCN stopped supplying the drugs gangs took over the neighborhoods and formed their relationships with cartels etc, the gangs formed their own relationships with their own suppliers no need to pay middle men when they can go direct to source for a better price.

Every ethnic group more or less controls the vices within their own communities and within their own people for a bunch of different reasons.

Chinese control the Chinese, The Hascid Jews control the Hascid Jewish neighborhoods ETC…

No surprises here.
