Human Trafficking.
"In strip malls across the U.S., illicit massage parlors have exploded into a $3 billion-a-year sex industry that relies on secrecy, close-knit ownership rings and tens of thousands of mostly foreign women ensnared in a form of modern indentured servitude"
Law enforcement officials said there were an estimated 9,000 illicit massage parlors across the country, from Orlando to Los Angeles. The epicenter of this national underground is the bustling Chinatown in Flushing, in the New York City borough of Queens. Women — typically Chinese, but also Korean, Thai and East European — arrive at Kennedy International Airport, learn the trade and are sent out to places like Virginia, Iowa, Texas and Florida. Women are recruited locally through ads in Chinese-language newspapers or over the social network WeChat.
