I think (sadly) you are giving too much agency to the circumstances of many prostituted women. Whilst economic considerations are undoubtedly a part of why some women enter prostitution a huge number (as in the case of the pp above) are groomed by abusive men from a young age and then become trapped in an abusive cycle that often includes drink and drug addiction.
These are generally working class and financially impoverished young women but they don't just wake up one day thinking ohh I know selling my body will be much better than a boring job in Starbucks, they are groomed and controlled by abusive men.
Well no Chinese peasant wakes up one day and thinks 'Oh I know what'll do: work twelve hours a day in a sweatshop' either. No one wakes up in East Africa and thinks 'Oh I'll go and work down a diamond mine I think' - but there is still an economic dimension to those people's situations.
I never for a minute suggested that women make a cold, calculated choice to become prostitutes, but economic pressures drive them into it, or make them vulnerable to bad people.
Of course there are fugitives from oppressive backgrounds as well as refugees from conflict zones who are targeted by gangsters. Sexual slavery and trafficking is a problem. But again this is mainly an issue with people who are displaced or homeless and therefore feel they have no other choice. There aren't many child prostitutes in Henley on Thames. Quite a few in Rochdale though.
Imagine a woman who has fled Syria and falls into prostitution. Do you think she gives a shit about the sympathy and gender politics of well-off liberals? No, she wants their money. She wants a job. She wants a safe place to live in a nice area. She wants well-funded social services and police forces. She wants not to have to do this horrible job.
You can go on about how men shouldn't sleep with prostitutes (and I think it's worthwhile to do so) but that in itself helps no one. Brutal, mercenary sex traffickers and pimps are not going to vanish just because we are willing them too.
What will hit the pimps is the transference of wealth from the rich to these poor people that they target. That will make real, tangible, concrete difference to people's lives. The Nordic model I think is good - but on it's own it will not work. It might work in what is still a fairly egalitarian social democracy like Sweden, but here it will not work so well.
Sorry everyone, but if we want prostitution and other social justices to be significantly reduced in the foreseeable future, then we have to take a cut. Fact.
