What are the positive effects of being a prostitute?

Answer 1

If you're one of the very few who remain in control of their life and work, with the freedom to select their customers, it can be a very well-paid job with only a slight risk of violence or disease.

The vast majority never attain this status, and are permanently at the mercy of the gangs, who like to get them hooked on drugs and into permanent debt. Eventually they settle for drugs, just to escape the misery, so their looks deteriorate, driving them into the lowest depths of existence.
