Discontent with class distinctions must arise so long as a man feels that his position in a class limits and cramps his capacities below the level of happier fortunes. Discontent is not altogether a bad thing, for it is often an _alias_ for hope; remove all discontent and you remove all guarantee for improvement. But discontent is of the malignant variety when it is allied with a sense of injustice; that is, of restrictions imposed upon one class for no assignable reason. The only sufficient reason for classes is the efficient discharge of social functions. The differences between the positions of men in social strata, supply some of the most effective motives for the struggle of life; and the effort of men to rise into the wealthy or the powerful class is not likely to cease so long as men are men; but they take an unworthy form so long as the ambition is simply to attain privileges unconnected with or disproportioned to the duties involved, and which therefore generate hatred to the social structure. If a class could be simply an organ for the discharge of certain functions, and each man in the whole body politic able to fit himself for that class, the injustice, and therefore the malignant variety of discontent, would disappear. Of course, I am speaking only of justice. I do not attempt to define the proper ends of society, or regard justice in itself as a sufficient guarantee for all desirable results. Such justice may exist even in a savage tribe or a low social type. There may be a just distribution of food among a shipwrecked crew, but the attainment of such justice would not satisfy all their wants. The abolition of misery, the elevation of a degraded class to a higher stage is a good thing in itself, unless it can be shown to involve some counterbalancing evil. I only argue that the ideal society would have this, among other attributes, and, therefore, that to secure such equality is a legitimate object of aspiration.
