If you’re wondering about my point of view on the whole question, I am sufficiently Paretian that I don’t find the exchange aspect of the relationship, or the passing of money, objectionable per se. (Assuming, of course, that neither age nor coercion is a concern, and often both are.) But it is still better, on the buying side, not to do it. Once you are aware of the kind of human stories behind the other side of the market, I would think it is hard to maintain an unflagging interest in the proceedings at hand. Nor do I think it would improve what happens in your life next. Yes the transaction does benefit the seller in many cases, but apply the Modigliani-Miller theorem and rebundle your action into a different blend of charity and erotic self-satisfaction, all toward The Greater Good.
