While traveling in Phnom Penh, Guy Jacobson encountered a barrage of young girls, some just 5-years old, aggressively soliciting prostitution.

They bear the look of street urchins, their eyes on the prowl for useful scraps of garbage and their bodies covered in clothes no cleaner than a mechanic’s rags.

The brothel business model is more vulnerable than it looks. There are ways we can make enslaving girls more risky and less profitable to push traffickers to quit.

The business model of forced prostitution is similar from Pakistan to Vietnam to the United States.
