Prostitution is prohibited under the pretext of maintaining “women’s dignity”. The truth is, prostitution is a very high paying job, not to mention one of the most enjoyable too. However, if prostitution is legal so will effectively polygamy, contract marriage, etc. The rich will just rent a lot and the rest don’t get any. That’s the real reason why prostitution is disallowed. It’s not because it’s a “too bad” job. It’s because it’s too good. Given choice, too many women would do it, too few will still want to get married.
