The facts are so patent that it is only necessary to call attention to them. We have, in modern times, seen many communities advance in population. Have they not at the same time advanced even more rapidly in wealth? We see many communities still increasing in population. Are they not also increasing their wealth still faster? Is there any doubt that while England has been increasing her population at the rate of two per cent. per annum, her wealth has been growing in still greater proportion? Is it not true that while the population of the United States has been doubling every twenty-nine[31] years her wealth has been doubling at much shorter intervals? Is it not true that under similar conditions—that is to say, among communities of similar people in a similar stage of civilization—the most densely populated community is also the richest? Are not the more densely populated Eastern States richer in proportion to population than the more sparsely populated Western or Southern States? Is not England, where population is even denser than in the Eastern States of the Union, also richer in proportion? Where will you find wealth devoted with the most lavishness to non-productive use—costly buildings, fine furniture, luxurious equipages, statues, pictures, pleasure gardens and yachts? Is it not where population is densest rather than where it is sparsest? Where will you find in largest proportion those whom the general production suffices to keep without productive labor on their part—men of income and of elegant leisure, thieves, policemen, menial servants, lawyers, men of letters, and the like? Is it not where population is dense rather than where it is sparse? Whence is it that capital overflows for remunerative investment? Is it not from densely populated countries to sparsely populated countries? These things conclusively show that wealth is greatest where population is densest; that the production of wealth to a given amount of labor increases as population increases. These things are apparent wherever we turn our eyes. On the same level of civilization, the same stage of the productive arts, government, etc., the most populous countries are always the most wealthy.
