If you go to the popular (well, poor) neighborhoods in northern Mexico you'll find thousands of young people, joining the cartels. The young people that don't, are idolizing the narcoculture: headache inducing narcocorrido music, big pickup trucks, cowboy attire, violent and arrogant behavior, etc. This has stopped being some clandestine business run by old families specializing in recreational agriculture export activities and has become an attempted takeover of society by the organized crime, at a level that makes Al Capone look like a beginner. In the controlled states most business and middle class independent professionals have to pay protection money to these guys or else. Bank employees provide all the required information. What about the police, army, government? Everybody knows they are in the payroll. It's more like Mexico during the later phase of 1910's revolution where all the young people joined one General or the other to survive while plundering, killing, raping, etc. Today the situation in the affected areas is controlled by terror. Psychological studies of the people doing terrorist activities have shown they're mostly "normal" people adapting to a new economic environment. In other words, young people are being recruited by the organized crime because the current economy is not providing quality jobs. I'll spare you the usual rant about the US-supported neoliberals elites blocking popular movements, but the fact is those elites want to go back to a semifeudal society controlled by the Church and Old Money, and are stopping any development that could empower the general citizens. If you've tried to do business in Mexico you realized how everything seems to be prohibited, or excessively controlled. What happens when you cannot honestly make a living? You do it unhonestly. And the elites have been doing a good job stunting critical education and lowering the level of popular culture through the TV chains like Televisa, so instead of becoming aware of who the real enemy is, young people unleash their frustration against their own.
