...the Confederation Congress and was always a debate over taxation—a debate over how much work does a slave do? Everybody agreed that a slave does not do as much work as a free person because the slave lacks incentive to labor. And southerners said, “Well, a slave only does half the work of a free person.” And the northerners said, “No, that’s too little. Well, a slave does three-quarters the work of a free person.” And so you split the difference—three-fifths. But now in the Constitutional Convention, it becomes a debate over representation. And so the positions of north and south reverse. Now the south wants the big fraction and the north wants the little fraction.
