Lives For Sale

I just saw a commercial for a movie starring Mira Sorvino called "Human Trafficking". I had heard that this kinda of thing happened, but really just thought it was an urban legend. It was something that parents told their children so that they wouldn't run away to the big city or go to these sleezy photo shoots and such.
Must be something that is pretty rampant for them to make a movie out of it. I think it is sick--what kinda whacko would buy a "person" for their satisfaction or for their disposal? Don't they know that karma ensures that things come back in "three-fold"? What are some people thinking?
Yuck and scary at the same time!
