Many of these girls are only here to make some money and go home.  Some of them had big debts and were led into this line of work - either knowing what it was or being misled - as a 'fast & easy' way to pay it back.  Most have families back home to support.  Most hate the work, some tolerate it and a few enjoy it with the small number of clients that are really nice to them.
The average AAMP provider will stay here for 4/5 months and probably not return though many do.
