As I look over the changes that half a century has wrought in the social life of my beloved country, I see some which awaken satisfaction--others which are not so exhilarating. The enormous and rapid increase of wealth is unparalleled in human history. In my boyhood, millionaires were rare; there were hardly a score of them in any one of our cities. The two typical rich men were Stephen Girard in Philadelphia and John Jacob Astor in New York; and their whole fortunes were not equal to the annual income of several of the rich men of to-day. Some of our present millionaires are reservoirs of munificence, and the outflow builds churches, hospitals, asylums, and endows libraries--and sends broad streams of charity through places parched by destitution and suffering. Others are like pools at the base of a hill--they receive the inflow of every descending streamlet or shower, and stagnate into selfishness. Wealth is a tremendous trust; it becomes a dangerous one when it owns its owner. Our Brooklyn philanthropist, the late Mr. Charles Pratt, once said to me: "There is no greater humbug than the idea that the mere possession of wealth makes any man happy. I never got any happiness out of mine until I began to do good with it." To the faithful steward there is a perpetual reward of good stewardship. No investments yield a more covetable dividend than those made in gifts of public beneficence. When Mr. Morris K. Jesup drives through New York his eyes are gladdened in one street by the "Dewitt Memorial Chapel" that he erected; in another by the Five Points House of Industry, of which he is the president, and in still others by the Young Men's Christian Association and kindred institutions, of which he is a liberal supporter. Mr. John D. Rockefeller is reputed to have an annual income equal to that of three or four foreign sovereigns; but his inalienable assets are in the universities he has endowed, the churches he has helped to build, the useful societies he has aided, and in the gold mines of public gratitude which he has opened up. Many of our most munificent millionaires have been the architects of their own fortunes. It is most commonly (with some happy exceptions) the earned wealth, and not the inherited wealth that is bestowed most freely for the public benefit. The Hon. William E. Dodge once stated in a popular lecture that he began his career as a boy on a salary of fifty dollars a year, and his board--part of his duty being to sweep out the store in which he was employed. He lived to distribute a thousand dollars a day to Christian missions, and otherwise objects of benevolence.
