Certain things will have to happen, before violent criminal organizations are eradicated from the world.
Firstly, if violent criminal organizations are to be eradicated, then the cartels that benefit from violence will have to be dismantled first. This may entail ensuring that only state agencies are involved in the arms business: because so long as that business remains in private hands, the folks behind it will always try to sow strife, so that they can sell more arms.
Secondly, if violent criminal organizations are to be eradicated, then social justice will have to be achieved first. Social justice doesn’t mean ending up with folks who are equal in all respects: people’s achievement will always vary, because different people have different abilities. Social justice does, however, mean that all people should have equal opportunity. It should, for instance, be possible for any person to register a company on, say, the portal, described on this article, without facing undue obstacles: regardless of whether or not the person in question is well connected with the powers that be.
Thirdly, if violent criminal organizations are to be eradicated, then the masses will have to start electing leaders who really care about their interests. Unfortunately, the masses are often fooled by party machinations, ethnic considerations and so on, to end up electing leaders who don’t care about their interests.
