In some parts of california they even have Pot dispenseries that arent legal and the cops arent busting them... I recant my comment.
Oil, Human Trafficking, Narcos, and Cash transfers from El-Norte are the biggest sources of foreign capital into the Mexican economy. They dwarf everything. The Cartels have a hand in all of the above"Mormon Drug War"--some background (disclaimer: 7 years old and VICE news, and therefore gay) video (this shit has been going on for a while) (and incidentally, the Mennonites in Canada were involved in trafficking drugs from Mexico)
The drug cartels have an inordinate amount of power and hold down physical control of parts of Mexico. The importance of this can't really be overstated. Drugs really have little to do with it as such anymore it's just a means of revenue for perpetuating statelike power within a state. Kidnapping is something that appeals as a terror tactic, and also for a profit motive.....which is one of the reasons that legalizing/decriminalizing drugs would not help the violence; the cartels, looking for other sources of income, would move on to kidnapping and people trafficking and other shit. And, fighting over a smaller piece of the pie, the violence would be WORSE! Indiscriminate violence like this is generally bad for business though especially on gringos so I would look for a deeper story than is generally being portrayed as to why these Mormons are involved. It would not be a good look for Obrador's still-new administration to allow carto blanco (so to say) to the gringos to fuck shit up south of the border. Obrador's drug policy is shit because it is all about centralization, which is to say making corruption easier, instead of having the Army, Navy, FJP, etc all quasi-independently undertaking their own investigations which was still a shit-show but gathering eggs into one basket is asking for the fox to guard it.
