Yep. That's how it works. Not every gang, but a good portion of them.
Like the Latin Kings are affiliated with Columbian drug lords. There's a new gang that has about 700 known members but I don't remember their name.
Ummm.... Quite a few of chicago's gangs were working for mobsters as well.
Basically, as drugs became the hot commodity and more and more mob families were getting in on the action, they needed to cover as much territory and get as much business as possible. The best way to do this was to target high school kids.
This guy at my job was telling me about his personal experience as he's from Newark, New Jersey.
A guy in a fancy suit, car, etc. (you know how it goes) approaches some teenagers with stree smarts and ask them if they want to make some money. What poor person doesn't want to make money? lol Especially teenagers that don't like school to begin with. They get a group together and start recruiting. Now if 10 guys come up to you and offer you money or an ass kicking, then you pretty much take the money. But in these days, they pretty much carried bats , chains and knives. It wasn't all that often in the 70's for gangs to carry guns. It's not smart. There also weren't laws about having a knife or bat on you. Guns is a different story.
High schools were perfect for gangs because they were full of fire extinguishers, electronic scales and other supplies which were essential for drug distribution.
