Any journey into the world, any research in literature, any study of society, demonstrates the existence of two distinct classes designated as the rich and the poor, the fortunate and the unfortunate, the upper and the lower, the educated and the uneducated-and a further variety of opposing epithets. Few of us who belong to the former category have come into more than brief contact with the labourers who, in the factories or elsewhere, gain from day to day a livelihood frequently insufficient for their needs. Yet all of us are troubled by their struggle, all of us recognize the misery of their surroundings, the paucity of their moral and esthetic inspiration, their lack of opportunity for physical development. All of us have a longing, pronounced or latent, to help them, to alleviate their distress, to better their condition in some, in every way.
