I don't think that is the best way to help prostitution. It might help a few few, and i mean very few women get out of it but once they're adults and have been doing this for a while it becomes a way of life. Just like most beggars out there. The problem still isn't with the women who are prostitutes, the people who deserved to be punished are the people from that girl's household who did her wrong. I'm very interested in social science and in my criminology class we learn why criminals do certain things and that is what we learned about prostitutes. To give a real life example, there was a young girl who had been raped by her mom's boyfriend, then again by her mom's second, third and fourth boyfriend. One day she just gets sick of it and runs away from home at the age of 15, now she's sitting on the side of the road and gets hungry, but she can no longer go to her mother's kitchen to get the food. So she sits there and thinks, she can't get a job cause she barely even went to school because her mom was a crackhead anyway who didn't care about her child's education, so therefore she has no skills. Plus she's too young to get a job anyway. Now there is only one thing she can do to get money so she sells her body. One day she gets arrested for that crime and the cops throw her in jail, but a juvenile officer looks deeper into the case, goes to her home and finds the real problem is there, and not with her. So they release the girl and put her into a foster home where she had nice siblings and parents who respected her. People didn't barge into the bathroom when she was there, she wasn't harassed or raped in any way and people truly cared for her. The cops went to go check on this girl 6 months later and saw she was trying out for her school's volleyball team and doing good at school.
Now the point of my long story was, for people to think twice before bad mouthing these poor women, and the OP is trying to do the right thing by helping them. What i want to let the OP know is, you can't help the grown women much, because prostitution is all they've known if they have been doing this for long enough and they couldn't learn anything because they didn't get as lucky as the girl in the story who had the opportunity to learn something else about the world. What you can do is help out households of girls coming from these places, or like someone said help out single mothers or women who fall into a similar category. I help raising money for abused women a lot. You should look into YWCA, they help women and by donating to them, will help them keep women from falling into prostitution.
