I think we "Happy Hookers" dominate the discourse because we're the ones who blog, or read MN, or organise conferences, etc.
I am not sure if it is feasible to actually obtain anything like accurate statistics on prostitutes.
There was recently a study done by someone at Leeds University and the Guardian had something about it last week:
www.theguardian.com/society/2015/feb/27/most-sex-workers-jobs-health-education-charities-survey
"Most Sex Workers Have Had Jobs In Health, Education, and Charities." That headline is just... stupid.
I answered that survey and I am pretty sure that the sample is a self-selected one of sex workers who read a particular support forum that is specifically meant to help independent escorts. That is how I found out about the survey. It was a computer-based, online survey. I think it's fairly reasonable to assume that this will bias the sample towards workers who have the means to learn of the survey and the inclination to fill it out. There may be value to data on that particular group of workers but as you can see, even the supposedly smart, educated people working for the Guardian are naive enough to come to the conclusion that this is "most sexworkers."
However, if you ask the police or women's shelters about prostitution, you will get an equally biased sample. OK, even Mumsnetters can need recourse to a shelter but I think it's as safe to assume that they are encountering a vulnerable group of women as it is to assume the Leeds study encountered a privileged group of women. I have a hard time articulating exactly what I mean, but I do feel that when discussing sex work, there is a distinction based on motivation. A "crack whore" will share several concerns with a "courtesan" but I would say that with the former, her primary issue is drug addiction with prostitution being just one issue related to that.
Obviously, women with little autonomy will not be heard as much as women with autonomy. Indoor prostitution can be much less visible, but they are generally the women who are more empowered to express their opinions and can do so more effectively.
My opinions on what I would like to see happen may often run contrary to what I think is just. For example, I wouldn't cry if the massage parlours in my city were shut down because they are competition for me and drive down prices and distort customer expectations. (Specifically, there is a parlour less than a mile from me where a man can get thirty minute's full service from an attractive woman for £35, and he can pop in with no notice. I can't operate that way.) However, I know girls who have worked in local parlours and there were valid reasons why they wanted to work in them. These women had a moderate amount of autonomy (that is, they could quit whenever they wanted but had a somewhat limited say in what they could refuse to do if they wanted to stay on the rota.) I have far greater autonomy because I am in a position to be able to sign a lease for a work flat and can manage my own business in a legitimate way. But not all women can do that for a variety of reasons and so it would seem churlish of me to say "If you can't work the way I do, then you can't work at all."
I'm sorry this is turning into such a long post!
The final thing I will bring up is that I am not entirely sure if everyone means the same thing when they say "pimp." I'm also not entirely sure if everyone means the same thing when they say "trafficking."
In my experience, by "pimp" many people mean anyone who makes money off the sex work of other people. If that is the case, then I have been pimped. I have worked in a massage parlour in another country. The owner charged punters a flat rate to pick a girl and go into a room with her and then we negotiated privately for sex, and the owner saw none of that money. I was happy to work there because it was a safe, comfortable, easy place to turn up and make money. I have also rented a room by the day from another prostitute in England. She was running a brothel and would therefor be defined as a pimp. However, I had full autonomy over everything I did and I was happy to pay her for use of the room.
In my experience, the pimps I have seen have been either emotionally abusive leeches (cock lodgers) or "players." The cocklodger pimp can be found anywhere: the women who are coerced or abused may work independently, at brothels, on the street... anywhere. "Players" are the classic stereotype of a pimp. That is to say, very well-dressed black men who proudly identify as pimps and stand around on street corners in America, boasting to one another about how hard their bitches work for them. It sounds like a caricature but I have seen them with my own eyes many times (I used to live in an infamous American red-light district). Again, the women who work with them - for reasons I don't fully understand - seem to have a surprising amount of autonomy in that they choose their pimps (status being linked to the status of their pimp) and have the ability to leave according to some bizarre code amongst the player culture. (I don't fully know how it works but I know that it is generally so.) If you are interested, seek out a documentary called Pimps Up, Ho's Down. You will never look at Ice T the same.
I don't know any parlour or agency owners, but they are also pimps - particularly as they advertise the women's services and rates and set the prices. As I said above, these women have full freedom to come and go, but if they want to work they must do so according to the rules set out by the pimp.
Obviously, the women who are enslaved and forced to work are hidden from us. Law enforcement encounters them but even they have limited access and what they look for and then report may be incomplete or biased according to various agendas that can shift with the times.
Trafficking is defined as "The recruitment, harboring, transportation, provision, or obtaining of a person for the purpose of a commercial sex act where such an act is induced by force, fraud, or coercion, or in which the person induced to perform such act has not attained 18 years of age," (sharedhope.org/learn/what-is-sex-trafficking/) and can be confused with other, voluntary forms of economic migration. in other words, a woman from a poor country may be brought to the UK to work as a prostitute but the question is down to how much autonomy she has. I think it's fair to assume that her position (poor, in a foreign country, and unable to work without the framework provided by a third party) puts her at a disadvantage and ripe for exploitation even if she readily and knowingly signs on to be brought in and set up in a flat with an adultwork profile. However, it still comes down to her level of autonomy and women all over the world deliberately seek to work in foreign countries for a variety of reasons. We can't assume that every Eastern European prostitute in the UK is trafficked.
Anyway, I will sum up thusly: when I hear "facts" bandied about about prostitution, I am often shocked and think "What the fuck are they talking about? That's not my experience and I don't know anybody who has that experience." When I read "90% of prostitutes are trafficked, pimped, and abused" it literally sounds as bizarre as something like, "90% of the women on mumsnet are alcoholics." Obviously, my own experiences are such that I don't see all aspects of prostitution and I concede that much goes on that I never know about. But it would be pretty hard to prove that 90% of mums netters are NOT alcoholics and I am pretty sure that finding out the true percentage would present quite a challenge to those those who gather statistics.
