Why does corporate bigness start to feel like political power?

In “Tim Wu: The Curse of Bigness,” Wu argues that antitrust is not just a technical consumer-price policy but a democratic tradition aimed at preventing concentrated private power from overwhelming citizens, markets, and politics. Using postwar Germany, the first Gilded Age, Brandeis, Theodore Roosevelt, and modern examples from cable, airlines, pharmaceuticals, tech platforms, and agribusiness, he makes the case for reviving anti-monopoly law as a way to restore accountable power and a more human-centered economy.
