I congratulate you upon the wonderful opportunity that lies before you. Happier than those of us who were obliged in earlier days to conquer the wilderness, you men of Argentina have at your hands great, new forces for your use. Changes have come of recent years in the world which affect the working out of your problem. One is that through the comparative infrequency of war, of pestilence, of famine, through the increased sanitation of the world, the decrease of infant mortality by reason of better sanitation, the population of the world is increasing. Those causes which reduced population are being removed and the pressure of population is sending out wave after wave of men for the peopling of the vacant lands of the earth. Another change is, that through the wonderful activity of invention and discovery and organizing capacity during our lifetime, the power of mankind to produce wealth has been immensely increased. One man today, with machinery, with steam, with electricity, with all the myriads of appliances that invention and discovery have created, can produce more wealth, more of the things that mankind desires, than twenty men could have produced years ago; and the result is that vast accumulations of capital are massing in the world, ready to be poured out for the building up of the vacant places of the earth. For the utilization of these two great forces, men and money, you in Argentina have the opportunity of incalculable potential wealth, and you have the formative power in the spirit and the brain of your people.
