Thats a very circumstancial point zapkin.
First, the girl has to be "found" by that "someone" that offers her the "job". The girl has all the choice in the world to say no.
And even, if the girl is that desperate for money, then I think the girl would be much better off doing that than ending as a street hooker.
I believe the thing works in the opposite way. Girls who WANT to do that actually LOOK for such jobs.
