It is legal to be a prostitute in Germany. That means if they have an official job they are entitled to certain benefits. What it doesn't mean is that anyone has to be a prostitute. It's only one option. And unlike in many other countries, it is an option within an appropriate legal frame. Not so many countries count prostitution among acceptable jobs.
