This depressing effect is not generally realized, for it is not apparent where there has long existed a class just able to live. Where the lowest class barely lives, as has been the case for a long time in many parts of Europe, it is impossible for it to get any lower, for the next lowest step is out of existence, and no tendency to further depression can readily show itself. But in the progress of new settlements to the conditions of older communities it may clearly be seen that material progress does not merely fail to relieve poverty—it actually produces it. In the United States it is clear that squalor and misery, and the vices and crimes that spring from them, everywhere increase as the village grows to the city, and the march of development brings the advantages of the improved methods of production and exchange. It is in the older and richer sections of the Union that pauperism and distress among the working classes are becoming most painfully apparent. If there is less deep poverty in San Francisco than in New York, is it not because San Francisco is yet behind New York in all that both cities are striving for? When San Francisco reaches the point where New York now is, who can doubt that there will also be ragged and barefooted children on her streets? This association of poverty with progress is the great enigma of our times. It is the central fact from which spring industrial, social, and political difficulties that perplex the world, and with which statesmanship and philanthropy and education grapple in vain. From it come the clouds that overhang the future of the most progressive and self-reliant nations. It is the riddle which the Sphinx of Fate puts to our civilization, and which not to answer is to be destroyed. So long as all the increased wealth which modern progress brings goes but to build up great fortunes, to increase luxury and make sharper the contrast between the House of Have and the House of Want, progress is not real and cannot be permanent. The reaction must come. The tower leans from its foundations, and every new story but hastens the final catastrophe. To educate men who must be condemned to poverty, is but to make them restive; to base on a state of most glaring social inequality political institutions under which men are theoretically equal, is to stand a pyramid on its apex.
