Not saying this is the case, but it seems you're referring to common gangbangers and drug pushers who live by the day, I'm not referring to those types at all. I know drug guys who are in they're 60's going strong that my grandfather came up with who aren't Italian or Jewish, serious guys that you'd never know what they were unless someone of a similar age group told you so. And if they did, they wouldn't say "hey, he's a major heroin supplier", it'd be something subtle like "you see that man, he was around when I was still doing what I did, serious guy, nothing like these ignorant guys you see running around", or like my grandfather likes to tell me "thats a REAL gangster". And you're just left to wonder "well who the fuck is that?"...And they don't have these big organizations, at least I don't think so, but hell if I know, but they mostly keep to themselves and a select group of people, in their late 30's or so.
