I've seen this documentary before. It's sad but I guess they just do it so they can make money off these business men.

And I agree with Kharon97, if there is a demand for it, it's not gonna stop. I figure that's why they just legalized prostitution in Amsterdam. There's also a town here in the UK that had legalized it in a specific spot.

As for young girls doing it, I guess it's somewhat pedophile related, and that is a growing epidemic all over the world, pedophiles are very very common that it's scary, to the point that there is now multiple 'pedophile hunters' popping up all over the place.
