Are sewer workers USED (and often abused) by other people for their own pleasure when they do their work? Completely different scenario.
The only people who think sex work is fine are those who dont do it and havent talked in depth to someone who has. I spent five years on the street making friends with girls and boys who did it to survive. There is NOTHING good about it. NOTHING. Its degrading, its soul crushing. Its VERY often accompanied by physical or psychological abuse which is why sex workers kept 'bad date' lists to warn other workers of the really creepy guys. Its a horrible way to make money but they did it because they didnt have any other way to survive. Next time you have rose colored glasses on about sex work, give me a call and Ill put you in touch with a 12 yr old girl who was pimped out by her 16 yr old sister and you can have a long discussion about the joys of sex work. Or with a 16 yr old boy who ran away from home and ended up getting sodomized by a man in a park because he needed 40 bucks to get a meal. Its really glamorous stuff, everyone loves it.
