The Asian nail salons in Florida are most often a front for sex trafficking, which is at an all-time high. Legalizing prostitution doesn't seem to have solved much, except, perhaps Nevada? It will not cut the underage trafficking and yes, it IS all about supply and demand.
However. Most of these women prostitute themselves to support their pimp or their drug habit or both. Maybe if we diverted (not "defund" which is a terrible word in and of itself) some police dollars to effective prevention we could lower the numbers.
I have never slept with a man for money but I understand that some women need better pay than MacDonald's is handing out and some women do it for love, but they're all doing it for survival.
