No, apparently not even war veterans have similar high rates of PTSD.

When you consider that even in countries like Germany it's almost exclusively poor women from other countries, often single mothers and/or already with mental health issues, who do sex work, I think it's very naive to believe the job is the same like flipping burgers or construction work. Or that these issues only stem from stigma and working conditions.

These jobs don't come close, though. They also don't attract primarily people who are already poor and mentally unwell to put them into a situation hard to leave that further increases their problems.
