It's good that people recognise that the prostitutes are just trying to make a living, selling their labour like everyone else. But it's difficult to see what there can be in the way of a permanent solution. Even the stopgap solution of getting the women 'off the streets' and licensing brothels, etc, is unlikely to end soliciting in the street. Brothels, sex lines,and such exist at the minute but not every man who wants to pay for sex is prepared to use them. From the point of view of the women themselves, though, this could certainly make life sAfer from the aggro of arrest and the attentions of the numerous psychos and vicious men who see protitutes as fair game.
Legalisation is also unlikely to happen in the current climate of moral repression.
Like other 'fringe economy' trade like petty theft, drugs, stolen goods etc, it often leads to people in areas getting pissed off that 'they are having to suffer'. But pushing them onto another community seems a small-minded way of dealing with it. Meanwhile richer men can always afford safer and more expensive surroundings if they want to buy someone's services. Targeting the women is just a way of shoving the problem out of sight. A good old british way of dealing with the problem.
