I think even in the USA the acceptance, if not legality, of sex work is very regionalized. In rural areas the local authorities spend a lot of time and resources going after sex work. In small town in the southern USA if they find out there is an establishment giving out HJs, there is a major police undertaking. Surveillance, undercover officers, etc. But in larger cities like NYC, Chicago, Philadelphia, SF, etc. I don't think anyone really cares.
