You keep quoting numbers, but you never talk about why those numbers exist.
In Queensland, the reason that number is so high is because the government has made it very hard and very expensive for brothels to go legal, and the majority that do go broke. It is more profitable to run an illegal one, than it is to operate a legal one. So though you are statistically correct, your reasoning is not.
Additionally, your own myth about strippers is demonstrably false. I know this because I used to be married to one and was involved in that scene on a personal level for many, many years. Here in NYC, some girls pull six figures. My ex-wife did. At one point she was making more than I was. While prostitution of some variety does exist in the legal strip clubs in NYC, it still was a relatively small number of women. Most of the girls that I've met and interacted with, which probably numbers in the 100's, fell into four broad categories: college students, party girls, single mothers and poorly educated immigrants. I would call none of them victims, nor would I ever call them exploited. Most of them are very shrewd, very business minded and are capitalizing on the only resources really afforded to them given their individual situations. In fact, the only sadness I feel about the entire thing is for the lonely men lining up to swallow whole the illusion that within the walls of these places they are wanted, sexually attractive, etc. It is pretty depressing to watch.
