America’s Economic Supremacy

Brooks Adams, in his work America's Economic Supremacy (1900), accurately predicted that the United States would achieve global economic dominance within fifty years, with only Russia as a comparable power. Adams's broader theory of history, outlined in The Law of Civilization and Decay, posits that centers of trade have historically moved westward, driven by population density and advancements in trade and industry.1

The United States is currently the world's leading economic power by gross domestic product (GDP), producing approximately one-fifth of the global economic output with less than five percent of the world's population. This economic size makes the U.S. a critical factor in international trade and a significant source of investment capital worldwide.2
