Mexico's most successful company is not among the top 10 Aztec corporations, nor is it listed in the legal commercial register. It's a consortium of drug cartels flooding the world market with illicit products, from cocaine to synthetic drugs and heroin, whose money has infiltrated 81% of the country's economic and social fabric.In the space of four generations, the Mexican smugglers of the 1920s have become the most influential mafia and financial powers on the planet. These capos are no longer artisans but multinational bosses in suits and ties, who use the Internet and heavy artillery, live in posh neighborhoods and are protected by men with "earpieces". This investigation plunges us into the heart of Mexican narco-business. The author paints a portrait of these men, sons of good families or peasants, who have become businessmen millionaires who cold-bloodedly eliminate anyone who gets in their way: judges, police, prosecutors, journalists, politicians... and competitors. Through this story, a country takes shape: daily violence, immigration, poverty, corruption, politics and the question of its future: narco-dictatorship or rule of law?
