> Do they not understand that prohibition benefits the cartels and funds their violence? Maybe they understand that argument, but disagree with it. I personally think it rather unlikely that legalization will lead to the dissolution of the cartels. In fact my first (paranoid, almost certainly wrong) thought was that the cartels had some sway with the Mexican Supreme Court. Most of the time the people who disagree wit…
Why would the cartels want to see Marijuana legalized in mexico?
The 'war' in Mexico is mostly cartel vs cartel, not unaligned government vs cartel.
So what do they have to lose? That means possible more consumption and possibly less pressure from the non-corrupt portions of the government and/or less legal power for one cartel to wield against another. (They'll have to stick with charges for the rampant human trafficking and slavery by the cartels.)
The idea that the cartels will just dissolve away upon the emergence of legal marijuana and a subsequent Free Market Flowering of the marijuana industry just seems hopelessly naive. Yes, the mafia was, perhaps, not happy about de-Prohibition. But guess what: the American mafia and is still responsible for the majority of organized crime in its area of influence. [1] The legalization of alcohol did not stop the mafia. And the cartels are far more ingrained in Mexican society than the mafia ever was in America. Even assuming someone unaffiliated with a cartel starts growing and selling, and the cartels don't just kill him, they would certainly run protection rackets.
