It’s an interesting perspective.

Human resources are still a problem for the cartels, unsurprisingly given that more than 10,000 employees are violently retired each year. Junior vacancies are easily filled from the pool of 10m ninis, youths who ni estudian ni trabajan (neither study nor work). But Mexico’s poor schools—the worst in the OECD—mean that drug exporters face the same problems as other multinationals in attracting highly skilled workers. ManpowerGroup, a recruitment consultancy, found that 42% of legitimate Mexican firms reported difficulties filling vacancies. Most said they had to recruit expatriates to senior jobs. This is also true in the drug business: the Zetas have turned to former members of Guatemala’s Kaibiles special forces to satisfy a growing demand for experienced killers. Visa requirements, at least, are minimal.
