France's new government proposes to "abolish prostitution".
What these measures would really do is force prostitution underground, hurting both prostitutes and their customers.
If you want to help people who feel they have been driven into prostitution, help them deal in other ways with the problems that drove them. That would be real help, and they would appreciate it. Some might then be able to stop doing prostitution. If others continue, voluntarily, why should you object?
