Poor women from Eastern Europe or other miserable areas are told by sex traffickers that they can make more money if they move to a new country and start a new career (such as dancing). They go into debt to the traffickers and soon find themselves living in a new area, without any ability to support themselves or speak the language. There is no other career. There is no dance career. They are FORCED by the traffickers into prostitution to repay their debts / stay alive. The women who are victims of trafficking are modern day slaves. They are not women who made poor life choices.
