"'But there was another way. And towards this the employer’s ideas began, first darkly and unconsciously, but now more and more clearly, to drift. Giving property, giving leisure, giving status costs money. But there is one human force that costs nothing. As it does not cost the beggar a penny to indulge, so it would not cost the employer a penny to employ. He could not alter or improve the tables or the chairs on the cheap. But there were two pieces of furniture (labelled respectively “the husband” and “the wife”) whose relations were much cheaper. He could alter the marriage in the house in such a way as to promise himself the largest possible number of the kind of children he did want, with the smallest possible number of the kind he did not. He could divert the force of sex from producing vagabonds. And he could harness to his high engines unbought the red unbroken river of the blood of a man in his youth, as he has already harnessed to them all the wild waste rivers of the world."
