Quote from Cutten:
Prostitution means that single men who would otherwise not get laid as much (if at all) can have sex when they like.
It also provides a much higher income for women than other jobs.
It's a fun profession for a nymphomaniac.
Couples can spice up their love life by hiring a hooker for a threesome or other activities.
Finally, men who would otherwise have affairs with mistresses, then fall in love with them and break up their family, can instead use a prostitute to get their sexual kicks. Given that falling for a prostitute is unlikely, this means that prostitution helps keep families together and prevents kids from suffering broken homes.
I used to live on a street that had several strip joints and knocking shops. Didn't bother me, since I was in an apartment and nothing was visible from the street. Also, since some of them were free (they put on strip shows so you would turn up and buy drinks), it was quite handy if I ever wanted to watch some attractive young women get their kit off. Would have been no problem for kids, since they wouldn't have seen it.
Outside the USA, many countries have legalized prostitution and don't suffer any particular societal breakdown. Most have far lower levels of violent and sexual crime, too. In the UK it is allowed in private (streetwalking is illegal). In many European countries there are specific red light areas where you can literally go "window-shopping" as the women are on public display. Again, if you don't like it, it's all in one place so you can just choose not to go there. Far from being crime-ridden dumps, these areas are often tourist attractions, and you see old ladies, couples and kids pointing and laughing about it all. Not everywhere is as sexually repressed as America.
