>> There will be those who choose it solely for economic reasons or other reasons, but I do not think that is the majority.
I do not pass judgement on anyone who is in that field *by choice* or *by necessity*.

It's just about 70 years now since the end of WWII, when just about every major city in Europe had been devastated physically and economically.
The nasty truth is that prostitution was the only means of support for tens of thousands of European families and if it hadn't been for the money given to those prostitutes by US GI's many of those families would have perished. Some of them were called "war brides" which was a euphemism for someone desperately trying to survive.

I saw the same thing, but a lot worse, in a country that I won't name in Asia, where virtually every house that didn't have a farm behind it (and some that had farms) was a family-run brothel where the parents were forced to put their daughters to work servicing US GI's.

In both cases, the countries had been ravaged by war and the cities had been basically laid low.
When I ride through Camden, NJ I see a lot of similarities to the cities that I saw in that country in Asia, including physical devastation and a high rate of prostitution.
