A former prostitute, now an anti trafficking activist, was saying that "when I was 5, I didn't dream of being a prostitute". I don't think that trash collectors didn't go into that profession because they dreamed at 5 of being trash collectors. You had a job you didn't really like, and never dreamed about? Welcome to humankind! Only a handful things are ever glamorous enough to be dreamed about by all or most 5 year olds...
Another woman, a current prostitute and pro legalization activist, said that the crackdown and law hardening on johns made her less safe: she had to decide in seconds whether to get in a potential client's car. She couldn't take her time trying to vet him because at any given time the police could be watching.
And the general deterrent effect of prohibition on reporting of abuse, or of suspects of known abuse, by all of prostitute victims of abuse, fellow prostitutes, and johns, is well known. So is the effect of prohibition in leaving prostitutes more vulnerable to recruitment by local organized crime and to engage in street criminal activity by themselves. Then again, there are no such things as unintended consequences.
