How ridiculous is it when I can go to any public place, establishment, business, etc and pick up a girl to take home for sex. But if I give her a dollar it becomes illegal. I don't see it being legalized in the U.S. because the government can't make money from a largely cash business. The government would seek to tax the hell out of the service to a point where it would be largely done underground, giving the industry legal protection for the service but leaving it to the government to ferret out tax evasion. When is the last time tax evasion was mentioned in any spa shutdown? Maybe never. And just about any business that operates largely on cash would fail a lie detector test if asked whether they had skimmed off the top. Every other vice crime has now become legal or largely ignored for prosecutions. The government has already screwed up on the legal marijuana trade. Taxed to death to open up a huge black market. Gambling is the emerging frontrunner for legalization of a cash business.
It is a fallacy to think we still have a moral compass in this country. A recent survey showed 40% of teenagers have no religion. And 25% of parents. Religion has been eliminated in discussions in politics and news coverage for years now. So I think the religious right is marginalized in fighting any legislations at any level that has the potential for government to make a buck from taxing it. But the political left, while having no problem with legalizing drugs, gambling, etc., still thinks every woman that wants to sell her body is doing so against her will. How silly, but not to say there aren't clear abuses on-going across this country.
My thought is that things will not change on legalization of sex workers. But I do believe there will be less focus on prosecution as demonstrated by NYC. Selective enforcement will continue to take place when political pressure in any given jurisdiction is called into play. If I am smart, I will continue to think with the big head.
