Why would anyone want to be involved in an organization where you more than likely will never ever meet the guy who runs everything?

There are just way too many people involved in Cartels and I don't think that is a very good thing in the long run for your career or personal lifespan. Whats the average lifespan of a cartel member? Do they even make it to the age of 18 without being killed or ending up in prison for a very long time? Highly unlikely.
