I get the point, but correlation is not causation.
I at least know of 2 girls who went the OF route because they wanted and liked it, one studied in my same school when we were kids and was considered the classroom's bitch by many at the time, the other one studied with a friend when we were in the university, they both say that they do it because they absolutely love sex, nothing to do with the money or the opportunities., same as any guy who says that he wants to be a porn actor when he grows up and ends up doing it.
I won't say that there aren't desperate people in that industry, but that has nothing to do with how our money works, after all, prostitution is an older profession than being a bankster and even older than FIAT money.
Not everyone wants a traditional family with kids where only the husband works (I certainly don't want that, nor does my girl), and that's not a consequence of money, but it's because people are different and following traditional values is not an obligation anymore.
