Burn!

Sir William Walker: Gentlemen, let me ask you a question. Now, my metaphor may seem a trifle impertinent, but I think it's very much to the point. Which do you prefer - or should I say, which do you find more convenient - a wife, or one of these mulatto girls? No, no, please don't misunderstand: I am talking strictly in terms of economics. What is the cost of the product? What is the product yield? The product, in this case, being love - uh, purely physical love, since sentiments obviously play no part in economics.

[general laughter]

Sir William Walker: Quite. Now, a wife must be provided with a home, with food, with dresses, with medical attention, etc, etc. You're obliged to keep her a whole lifetime even when she's grown old and perhaps a trifle unproductive. And then, of course, if you have the bad luck to survive her, you have to pay for the funeral!

[general laughter]

Sir William Walker: It's true, isn't it? Gentlemen, I know it's amusing, but those are the facts, aren't they? Now with a prostitute, on the other hand, it's quite a different matter, isn't it? You see, there's no need to lodge her or feed her, certainly no need to dress her or to bury her, thank God. She's yours only when you need her, you pay her only for that service, and you pay her by the hour! Which, gentlemen, is more important - and more convenient: a slave or a paid worker?
