Living in abject poverty, $10,000 is a beguiling promise. All you have to do is give up one kidney. It’s ok, you have another one. But a Bloomberg Markets Magazine investigation shows how gangs around the world prey on the poor and use threats and violence to get them to give up their organs, which they can then resell for upwards of $150,000. This isn’t just happening in some ice-filled bath in China: this week, a Brooklyn man plead guilty to selling black market kidneys to people in New Jersey.
