"If we are going to say prostitution is illegal, why are so few men prosecuted for it? The answer is because they are powerful, well-connected, and can afford expensive lawyers that can keep their names private. ... becoming 'tough on prostitution' is likely to fail in the same way becoming 'tough on drugs' has."

Though I'm not a fan of the sex worker career path, I believe Kay makes an important point. Prosecuting prostitution does very little to address the source of the problems at the root of the success of said industry.
