Such conditions gradually brought about a profound discontent, a grouping of classes. Among the comparatively prosperous there was set up a social competition in luxury that was the bane of large and small communities. Skilled labour banded itself into unions, employers organized to oppose them, and the result was a class conflict never contemplated by the founders of the Republic, repugnant to democracy which by its very nature depends for its existence on the elimination of classes. In addition to this, owing to the unprecedented immigration of ignorant Europeans to supply the labour demand, we acquired a sinister proletariat of unskilled economic slaves. Before the war labour discovered its strength; since the war began, especially in the allied nations with quasi-democratic institutions, it is aware of its power to exert a leverage capable of paralyzing industry for a period sufficient to destroy the chances of victory. The probability of the occurrence of such a calamity depends wholly on whether or not the workman can be convinced that it is his war, for he will not exert himself to perpetuate a social order in which he has lost faith, even though he now obtains a considerable increase in wages. Agreements entered into with the government by union leaders will not hold him if at any time he fails to be satisfied that the present world conflict will not result in a greater social justice. This fact has been demonstrated by what is known as the “shop steward” movement in England, where the workers repudiated the leaders’ agreements and everywhere organized local strikes. And in America, the unskilled workers are largely outside of the unions. The workman has a natural and laudable desire to share more fully in the good things of life. And it is coming to be recognized that material prosperity, up to a certain point, is the foundation of mental and spiritual welfare: clean and comfortable surroundings, beauty, rational amusements, opportunity for a rational satisfaction of the human instincts are essential to contentment and progress. The individual, of course, must be enlightened; and local labour unions, recognizing this, are spending considerable sums all over the country on schools to educate their members. If a workman is a profiteer, he is more to be excused than the business profiteer, against whom his anger is directed; if he is a spendthrift, prodigality is a natural consequence of rapid acquisition. We have been a nation of spendthrifts.
