Along with Edward Achorn‘s Projo op-ed on the state of prostitution in Rhode Island (or maybe that should be on the state of prostitution, Rhode Island), you may want to read this blog item written by Brad Plumer and recommended by Reihan Salam. The post points to a mountain of evidence showing that legalizing prostitution doesn’t transform it into just another legitimate business. From Plumer’s post…

In 2003, the Scottish government, looking to revamp its own prostitution laws, did a massive report on different policies around the world, and discovered that legalization-plus-regulation comes with its own set of problems.
The study found that, as you’d expect, legalization often led to a dramatic expansion of the sex industry: In Australia, brothels proliferated to the point where they overwhelmed the state’s ability to regulate them, and became mired in organized crime and corruption. In many countries, child prostitution and the trafficking of foreign women also increased dramatically. More importantly, surveys found that many sex workers still felt coerced and unsafe even after decriminalization. In the Netherlands—often held up as a model—a survey done in 2000 found that 79 percent of prostitutes were in the sex business “due to some degree of force.”

Yet wherever there is regulated prostitution, it is matched by a flourishing black market. Despite the fact that prostitution is legal in 12 Nevada counties, prostitutes continue to work illegally in casinos to avoid the isolation and control of the legal brothels. Even the legal brothels maintain a business link with the illegal pimping circuit by paying a finder’s fee to pimps for bringing in new women.
