Part 1: The Fallacy of Zero-Sum Economics

  1. On the nationalist shift: "The belief that a nation must gain narrow benefits by cheating everyone else is a fundamental analytical fallacy." — Source: Foreign Policy
  2. On economic interconnectedness: "Because international trade is not a zero-sum game, even when other countries gain a larger share of high-value-added production, it ultimately benefits domestic consumers through lower prices." — Source: ITIF
  3. On the risk of conflict: "A zero-sum mindset echoes early twentieth century mercantilist rhetoric, which historically contributed to the breakdown of international cooperation and escalation of global conflicts." — Source: Cato Institute
  4. On political consensus: "Politicians across the political spectrum have unfortunately converged on seeing the global economy as a zero-sum competition." — Source: LSE

  6. On false accounting: "America's zero-sum economics doesn't add up, as it ignores the historical benefits the United States gained from leading a rules-based system." — Source: Foreign Policy
  7. On self-sabotage: "Attempting to weaponize economic relationships often backfires, damaging the very industries policymakers claim they want to protect." — Source: Washington Post
  8. On global growth: "When trading partners grow richer, they become better customers for exports, not simply fiercer competitors." — Source: PIIE

  6. On economic security: "Redefining almost every aspect of trade and investment as a matter of national security paralyzes normal commerce and invites systemic inefficiency." — Source: Cato Institute
  7. On emerging markets: "The fracturing of the global order threatens to lock emerging economies out of the export-led growth models that lifted hundreds of millions out of poverty." — Source: NUS
