It is true that class loyalty may, to some extent, enlist a spirit of group devotion and militant ardor; but it does not, for the majority offer the conditions needed to awake enthusiasm, and I do not see how it ever can. Social classes, make what you will of them, have not separate cultures, traditions, or currents of daily thought, and are not likely to have. The class spirit has not been successful in subordinating the spirit of nationality, even in time of peace; while in time of war, or in the case of nationalities struggling with oppression, like the Belgians, the Poles, or the Bohemians, class becomes quite a secondary matter.[61] The growing economic solidarity of classes tends in the same direction. We hear it said with equal confidence that the interests of capital and labor are opposed, and that they are the same. The solution, of course, is that both statements are true. The two have a common interest in the prosperity and stability of industry, and are mutually dependent upon each other’s efficiency and fair dealing. At the same time there is a real conflict of pecuniary interest as to the division of the product. In general the solidarity and interdependence increase as industries become more extensive and intricate, and require more intelligent and harmonious co-operation. It is also increased by the diffusion of investment, thrifty wage-earners becoming, to a large and increasing degree, small capitalists as well. The outcome is an organic whole which does not exclude opposition, but tends to limit it to what is functional, and to bring it under the control of rule. Under such conditions the relation between economic classes—capital and labor, let us say, for simplicity—is that of two parties to a bargain so advantageous for both that neither can afford to throw it up, but whose precise terms are matter for controversy. Each side may have a motive for disputing, for feeling out the other’s position, even for temporarily refusing to trade, but not for going to extremes. Neither can afford to push the other to desperation. Capital could starve out labor, and labor could wreck the whole system, but in either case it would be suicidal to do so.
