Who wants a quicky

Sin city (Las Vegas) is known for gambling and prostitution, even though selling skin is illegal in city limits. So why is prostitution so frowned upon in other parts of America? Is this a victim-less crime, or does it contribute to the moral downfall of society which will send us all straight to hell? How does religion play into this occupation, and how do politics. Is it possible that prostitution has remained illegal to provide jobs for officers which would otherwise serve no purpose? We have all seen cops where one officer dresses up like a street walker and they bust suspected johns, does this actually have any social benifit, or is it just a bunch of guys playing dressup?
