I guess they are like a government, in that they can afford to wait out disputes while the drug businesses can't. Every once in a while these other groups will try and get rid of the dominant extortion gang but since they live off skimming, and their business model is a vehicle and a gun, they can afford to go to war while the drug dealers and cartels all will be losing money and cannot sustain a lengthy conflict. The narcotics businesses have extensive bribery networks they need to keep operating to survive and any interference in the income will threaten to unravel it all. Some of them have minimum wholesale they need to buy every month in order to keep up supply, and customers will also start calling competitor lines if deliveries are stopped.
Even worse, when the heat on the streets is so hot during a war from all the shootings and police are everywhere, not much business can happen so the extortion crews turn to contract hits for income. For $10-15k you can pay them to kill off one of your rival drug dealers, potential informants or even people in your own delivery crew so you can move up and take their place. So while they are fighting off a rival takeover they are also open for local business dropping bodies all over the streets and blaming it on the invading gang, which police then turn their attention to, and are getting paid while the rivals/cartels are bleeding money. Eventually they have no choice but to give up the dispute to save their own business from extinction, much like how businesses have to settle in court when defending against government lawsuits and can't afford too much delay.
What is really surreal about the black market is after these violent outbursts everything is simply settled by a payment of back taxes owed and you just go back to work like nothing happened. One of the enforcers who managed us was shot at repeatedly by somebody he knew living in the same immediate neighborhood during one of these wars and next week it was all cleared up above us by whoever was in charge and beefs squashed. He'd still see the guy on a regular basis, no hard feelings, only business.
I am both an aspiring graduate student (though, maybe not after reading this) and grew up with many friends who were/are still in organized crews, plus did some delivery for a few years myself when I was a foolish 17 yr old.
Most delivery driver jobs here pay $150-200/day depending on how busy the line is, and the people that work them usually aren't looking to move up instead they want cash wages for easy work, since most have records and can't get decent paying jobs anywhere else. The article is correct almost all these guy's still live with their parents. There were only 2 guys I knew that actually thought they could move up and make big money while the rest of us accepted we were only ever going to make $200/day and were essentially contractors, we were never privy to any gang internal business.
Gangs no longer hold drugs when corner selling (where you make the most money, selling by the point at full street value), they pay an addict in drugs to do this while they run security watching over the operation to prevent robberies. Street enforcer is where you start if you want to move up since you are essentially managing operations instead of just a delivery boy. You also hang around the top people as they call on you to come along to jack rival operations. These thugs get a lucrative percentage when they steal drugs off other crews and pass them down to the delivery lines to sell so are making real money, since it seemed every enforcer in my little dope crew was bombing around in a Porsche Cayenne customized to be bullet resistant with hidden compartments installed to hide their handguns, lived in huge houses by themselves and were always decked out in latest heatbag designer clothes. I don't remember any of these guys being broke, and technically they are the lowest rung on the gang hierarchy since the drivers are just contractors.
That was back in 2005 though, and now the vast majority of gangs are not handling any product here. Their income model is intimidation and extortion. It's far easier to wave a gun around on the street and tax everybody in the drug business than it is to put in work building up a line or managing operations. They don't even steal each other's lines anymore, just demand a percentage of the profits. As a result street violence has actually declined, since jackings and hits decreased and most beefs are now solved by passing money over a table. These independent dealers are also way better at selling drugs than gangs, so bring in much more money and the dominant gang that taxes them also offers protection from robbery (we are robbing you to offer our robbery prevention services).
This gangster method is more profitable, has almost no startup costs besides needing vehicles and guns, is much harder to prosecute since they never are directly involved in narcotics trade, and has an endless recruitment pool inside prisons to replenish ranks faster and with tougher recruits. It's also how all those Mexican border cartels operate. They are merely taxing the smuggling routes into the US skimming the shipments of Gulf and Sinaloa cartels. Those cartels have to build manufacturing, supply chain and retail while paying off politicians and police while the thug at the border just needs a gun, and is impossible to get rid of since they hold down their territory hard.
tl;dr Stepping into a gang as the new lowest position pays much more now, and is almost a guaranteed ladder to better positions since narcotics handling has all been outsourced as drug dealers are good at being drug dealers, and gangsters are good at being thugs.
