If we were to look at this as a legitimate job and we were to have job fairs at universities, I highly doubt this would be a successful job fair booth that we would want to see as options for our children in future generations to be going to.
I would not want to see it legitimized in any way so that we would be telling our children that if they had one job at McDonalds and couldn't work anywhere else, a brothel was available, and that rather than going on EI they would be compelled to work at that brothel. I don't think any MP here would want that option for their children either.
That comes along with the concept that this is a legitimate choice, a decent work place, and equal power. We're not talking about morality, but about a power indifference here. We already know about the high rate of missing and murdered native women, because they're targeted for their race and gender, as they're seen by society as devalued and disposable. If society doesn't care about the missing and murdered, how is it possibly going to care about native women who are in prostitution, and how do these women have real choices?
