That phrase could be loosely translated as "That who doesn't do dishonest deeds in prejudice of other people cannot advance in life".
If that's a philosophy that the you want to learn, then please take Carlos Slim as a role model because he is the poster child of that ideology.
Whenever I hear the news that Carlos Slim is the richest man in the world I cringe. Bill Gates? I think the guy somewhat deserves his millions, Microsoft business practices may be morally-gray, but they have helped shape the world the way it is now. Bill Gates had change the world.
Carlos Slim has done nothing, absolutely nothing, good for the world, not even for Mexico. He is the product of a corrupt system whose only merit is being the best exploiter of his people.
If this looks like a good role-model, you are going to love Joaquin Guzman Loera. I'm waiting his letter to the young people.
