It is an urban legend that these women have no other options than prostitution. At most locations, this is false, they have. The other options don't pay as well though. These girls prefer relatively well-paid prostitution over working 10 hour shifts at a factory or selling food stuff on markets. If there are no other options, all the ugly girls and lowly educated men would die of starvation. Yes they are exploited, but how did they get there? All the high-profile stories about human trafficking and prostitution slavery, in the end it's only a small minority.
