Street legal

Prostitution is inevitable, so we might as well legalize and regulate it. That’s a pragmatic argument that I used to find persuasive. If brothels were legalized and inspected, I believed, then we could uproot child prostitution and reduce AIDS and sexually transmitted infections.

I changed my mind after looking at the experiences of other countries. The Netherlands formally adopted the legalization model in 2000, and there were modest public health benefits for the licensed prostitutes. But legalization nurtured a large sex industry and criminal gangs that trafficked underage girls, and so trafficking, violence and child prostitution flourished rather than dying out.

As a result, the Netherlands is now backtracking on its legalization model by closing some brothels, and other countries, like Bulgaria, are backing away from that approach.
In contrast, Sweden experimented in 1999 with a radically different approach that many now regard as much more successful: it decriminalized the sale of sex but made it a crime to buy sex. In effect, the policy was to arrest customers, but not the prostitutes.

...the evidence is strong that the new approach reduced trafficking in Sweden, and opinion polls show that Swedes regard the experiment as a considerable success. And the bottom line is that if you want to rape a 13-year-old girl imported from Eastern Europe, you’ll have a much easier time in Amsterdam than in Stockholm.

Many feel sex slavery is particularly revolting -- and it is...In a Bucharest brothel, for instance, I was offered a mentally handicapped, suicidal girl in exchange for a used car. But for every one woman or child enslaved in commercial sex, there are at least 15 men, women and children enslaved in other fields such as domestic work or agricultural labour. Recent studies have shown that locking up pimps and traffickers has had a negligible effect on the aggregate rates of bondage. And though eradicating prostitution may be a just cause, Western policies based on the idea that all prostitutes are slaves and all slaves are prostitutes belittles the suffering of all victims.
