I became good friends with one of my former ATF's, who in her "real life" worked at a shelter for pimped and trafficked women. The shelter was very progressive: after getting the girls away from their pimps, pushers, etc. she would teach them to set up a website and work for themselves (only the ones that were still interested in staying in sex work). Her center was quite busy, and there was no shortage of ladies to be rescued. Even worse, these ladies not only suffered physical and psychological abuse, but the pimps charged them for housing, food, protection, advertising (ha!), etc. and in most cases the ladies OWED money to the pimps even after working all day and night.
There is probably a difference between forced prostitution which I suspect is a lot more rare, and what I saw going on in her rescue center. Most of the ladies that came into the rescue center may have started out in sex work of some kind as a choice (maybe for food, maybe for drugs, or maybe encouraged by a boyfriend to do so) but then got stuck in the cycle that the predatory pimps and traffickers have setup for themselves. Some foreign women came here knowing they would be sex workers, but were told they would be "free" after paying their "debt" (which of course is never paid since all of the "charges" keep the debt from ever being reduced). It is a lot worse than just "economic slavery" and that kind of thing does need to be addressed, and is pretty common especially with BP and Craigslist.
So, I don't really have a problem with taking these operations (the pimps and traffickers) down, just like I wouldn't have a problem with taking down a forced labor shop (these exist too, still). But you really have to be careful because it is so easy for the media and politicians to try to paint all sex work as being a part of that. Rather than focusing on the evils of pimps and traffickers who lie, cheat, beat, coerce, drug and enslave sex workers .. the focus of these opportunists is on the sex workers.
