Allie knows that there is a price to pay for prostitution. Society's judgment is something women in the sex industry will have to negotiate for themselves. Dubner and Levitt are also aware that their professional respect for Allie's business aptitude is, in its own way, controversial.
"I think one of the broader implications of this working on prostitution and -- and knowing that women will cross over from being, you know, working in McDonald's to being prostitutes -- is people say, 'Well, these women are exploited, you know, and, and it's a terrible thing,' said Levitt. "But if you took these women -- their opportunities away from being prostitutes -- will they be better off? They are choosing to be prostitutes because they think it's better, a better track than the other thing to have."
For this economist, however, the unquantifiable nuances of morality seem to factor out of the equation.
"I think that -- you know, and having studied this -- that the, the question that comes to my mind always, it's not, 'Why would a woman go and be a high-end prostitute?' but just the opposite: 'Why are there so few women who are out there being high-end prostitutes?" said Levitt.
It's a question Allie has considered, even as she wonders what advice she would give if she had a daughter.
"I thought about this a hundred times," she said. "And, this goes back to this whole morality thing. I feel like if I had a daughter, I would want her to be in charge of her own sexuality. Her own. No matter what it is that she decides to with it. But if I had a daughter, I would hope that I could give her, you know, all the skills in the world that she would have so many different opportunities that this would just be one of many, many that would give her all the same wonderful things out of life."
After 10 years as a call girl, Allie is making another choice. She quit the business and went back to school to study something that would give her all the skills in the world.
"Economics, of course," she said.
