Is Trump Eroding America’s Global Supremacy?

The Looming Question of American Hegemony

The United States is currently navigating a period of significant economic and institutional shifts that have prompted comparisons to the historical decline of the British Empire. While the U.S. maintains a position of global economic leadership, policies regarding immigration, scientific research, and international trade are sparking debate among economists and historians about the long-term sustainability of American hegemony.

Foreign Talent and the AI Advantage

A primary driver of U.S. technological and economic dominance has been its ability to attract high-skilled global talent. Immigrants have played a disproportionate role in American innovation, with 35 percent of the 410 Americans who won the Nobel Prize in chemistry, medicine, economics, and physics from 1901 to 2024 being immigrants, and 59 percent of America’s “unicorns”—private start-ups worth more than $1 billion—having at least one immigrant founder or co-founder.

The U.S. currently leads the world in artificial intelligence research, a sector heavily reliant on foreign-born experts. 59 percent of the world’s top AI researchers work in the U.S., and more than 65 percent of them are foreign-born. Current policy discussions regarding H-1B visa programs and potential restrictions on student visas for international Ph.D. candidates have raised concerns among industry leaders that tightening these pathways could reduce the pipeline of talent necessary to maintain a competitive edge in emerging technologies.

The Dollar and the Risks of Protectionism

The status of the U.S. dollar as the world’s primary reserve currency remains a cornerstone of American economic power. This position is supported by the perceived stability of U.S. institutions and the independence of the Federal Reserve.

However, recent shifts in economic strategy—including the increased use of tariffs and changes to fiscal policy—have prompted scrutiny. When nations shift toward protectionist trade measures, the resulting impact on supply chains and the cost of goods can alter the global economic landscape. Historical precedents, such as the gradual loss of the British pound’s dominance following the post-World War II era, are often cited by economists to illustrate how shifts in industrial output and trade alliances can affect a nation’s long-term financial standing.

Institutional Integrity as an Engine for Growth

Long-term economic growth is closely tied to productivity, which is largely fueled by scientific advancement and research. The National Science Foundation (NSF) serves as a major engine for basic research that drives private-sector innovation.

Recent federal budget debates have focused on the allocation of funds toward non-defense research. Economists such as Daron Acemoglu and James A. Robinson, authors of Why Nations Fail, argue that the strength of a nation’s institutions—specifically the protection of property rights and the maintenance of competitive markets—is the most reliable predictor of long-term prosperity. Any significant reduction in federal support for scientific research or perceived political interference in independent regulatory agencies can, according to this framework, impact the pace of future technological breakthroughs.

Strategic Pillars of National Prosperity

• Talent Acquisition: The ability to retain foreign-born researchers remains a critical factor in the U.S. AI sector.
• Institutional Independence: The stability of the Federal Reserve and the rule of law are essential for maintaining the dollar’s status as a global reserve currency.
• Productivity Trends: Economists generally agree that long-term improvements in standard of living are tethered to productivity gains, which require consistent investment in research and development.
• Global Trade Dynamics: The shift toward or away from international trade alliances impacts the efficiency of global supply chains and the cost of domestic production.

As the U.S. continues to manage its economic trajectory, the tension between domestic industrial policy and maintaining an open, innovation-driven global environment remains a central focus for policymakers and economic analysts alike.
