Yes. Partly on the grounds rarely mentioned that it would help women re-access into 'the system' and help them find more suitable forms of employment (the first person to say, yes I suspect it will be Opebo, that most women choose to prostitution is going to get a very large internet boot in the face).
Most women working in the industry
did choose to.
Whether they would have if they'd had a clearer view of the working conditions is a different matter entirely.
And most do get out again reasonably quickly. Without help from the Government.
I am, of course, once again talking only of conditions in brothels in Western Europe. That's the part I'm knowledgeable about.
One other angle needs to be mentioned - one other reason why the industry prefers the current state of affairs to anything that could be called normalcy.
Normalcy would involve paying taxes.
