Chuh!
Well, I'll say it, because I don't really believe any of this, but Yes I object on "moral" grounds.
This young woman, not yet into her 20's, is not really making a "choice" is she? Your posts are contradictory in the extreme.
(I'm paraphrasing here for the sake of my mental health)
First you say "Well, she's going to do it because she can't afford the rent in any other way, she can't get a job because she got done for shoplifting at age 15" (which BTW would have no bearing on her getting a junior job in an office for example)"
Then you say: "She is happy with her choices and I'm just winding you all up she'll earn shedloads!"
This young woman is being failed in every way as far as I can see. Failed by her father, failed by her step-father, failed by her mother, and failed by THE SYSTEM; and now failed by you. And that is what I find morally repugnant.
Rather than spending your internet minutes checking out the agency, why not LOOK at direct.gov.org and really find out what she'd be entitled to? What about looking at Gumtree for example to show her houseshare options, where the rent is much lower than standard rentals. How about finding other options rather than this? How about listening to what we're saying? Because you've had a pretty much unanimous response from MN here (surprise, surprise, parents on a parenting site disagree with a damaged 19 year old going into prostitution) and why you keep banging on about choices and career fucking options is just, well, it's pretty lame.
