Indeed, this type of ability was never in such demand as it now is, for the conduct of the vast and diverse social structures rising about us—industrial enterprises, political parties, labor unions, newspapers, universities and philanthropies. It has its high money value partly because of its rarity and partly because there is a regular market for it; the need being so urgent and obvious as to create a steady and intelligent demand. In this latter respect it contrasts with services, like moral leadership, which people need but will seldom pay for. A third reason is that its possessors are almost always clever enough to know their own value and secure its recognition. In discussing the power of the capitalist class there is no question of the finer and higher forms of power. We shall rarely find among the rich any pregnant spiritual leadership, theirs being a pedestrian kind of authority which has a great deal to do with the every-day comfort of their contemporaries but does not attempt to sway the profounder destinies of the race. Nor does the world often accord them enduring fame: lacking spiritual significance their names are writ in water. Even in industry the creative thought, the inventions which are the germs of a new era, seldom come from money-winners, since they require a different kind of insight. The capitalist represents power over those social values that are tangible and obvious enough to have a definite standing in the market. His money and prestige will command food, houses, clothes, tools and all conventional and standard sorts of personal service, from lawn-mowing to the administration of a railroad, not genius or love or anything of that nature. That wealth means social power of this coarser sort is apparent in a general way, and yet merits a somewhat closer examination. We have, first, its immediate power over goods and services: the master of riches goes attended by an invisible army of potential servitors, ready to do for him anything that the law allows, and often more. He is in this way, as in so many others, the successor of the nobleman of mediæval and early modern history, who went about with a band of visible retainers eager to work his will upon all opposers. He is the ruler of a social system wherever he may be.
