““Moreover, the labor of the exploited peoples round the Equator is not really necessary to the world's economy. They add nothing to the wealth of the world, since whatever they produce is used for purposes of war, and the object of waging a war is always to be in a better position in which to wage another war. By their labor the slave populations allow the tempo of continuous warfare to be speeded up. But if they did not exist, the structure of world society, and the process by which it maintains itself, would not be essentially different.””
