I'd like to see an answer to why we wouldn't devolve into a situation where women and men would be coerced into prostitution by the unemployment system by the prospect of losing benefits.
If it's a legal line of work, and the government is desperate enough to get people off the unemployment rolls, I don't see how you could stop it.
The ACLU would weigh in on this--on the side of the government. They have supported legal prostitution and porn for years, and support forcing prolife medical personnel to participate in abortions. I can't imagine them not supporting the government in a situation like this in Germany.
How many Helen Thomas's look alikes in the profession would it take ?
