North Korea's Secret Slaves: Dollar Heroes (2018)

Asphyxiated by international sanctions, the North Korean government has set up one of the world's largest systems of forced labor: 70,000 people are employed in a dozen countries in order to provide foreign currency to Kim Jong-un's regime. Attracted by the prospect of a high salary, these 21st century slaves find themselves forced to work fourteen hours a day in sometimes inhuman conditions, under constant surveillance and far from their families. As for their income, most of it is taken by the North Korean state. This system benefits Pyongyang, which finances its nuclear program in particular, but also agribusiness and construction companies.
