Daron Acemoglu's Diagnosis: Liberal Democracy Is Dying of Self-Inflicted Wounds

Nobel Prize-winning economist Daron Acemoglu has written what may be the most ambitious entry yet in the crowded 'liberalism-in-crisis' genre. His new book, What Happened to Liberal Democracy? Remaking a Politics of Shared Prosperity (published August 11, 2026, by Penguin Random House, 416 pages), argues that the greatest threat to liberal democracy is not populism, authoritarianism, or social media — it is the system's own internal failures . Where others blame external forces, Acemoglu makes a more incriminating argument: liberalism is dying primarily of self-inflicted wounds .

The Central Thesis: A Self-Inflicted Crisis

Acemoglu's central claim is that liberal democracy flourished precisely when it delivered on its core promises: broad-based economic gains, inclusive democratic governance, and the free pursuit of knowledge . The system faltered when it stopped doing so. The book traces how liberalism — a philosophy built to challenge power — never fully adjusted to becoming the establishment ideology of the 20th century, and lacked the resilience to deal with the shocks of globalization and digital technologies .

The 'Soft Straitjacket': How Elites Narrowed Democracy

Acemoglu describes a mechanism he calls the 'soft straitjacket' — not overt repression, but a gradual, elite-driven narrowing of political and economic choices that constrained democratic debate and systematically excluded working-class concerns . This manifested in three key failures:

• Abandonment of shared prosperity: Liberal elites presided over rising inequality and stagnant wages for non-college workers, especially after the 1980s when automation, globalization, and deindustrialization severed wages from productivity growth .
• Elevation of a college-educated elite: Policy and culture drifted toward the priorities of professionals and credential-holders, alienating the very working class that had once been the core constituency of progressive liberalism .
• Drift away from free expression and democratic self-government: Institutions became less responsive to popular will, and the culture of open debate eroded. Acemoglu notes that 85% of American voters feel that 'elected officials do not care what people like them think' .

This soft straitjacket suffocated the democratic responsiveness that once gave liberalism its legitimacy, making it vulnerable to populist backlash .

AI Dysfunction as a Mirror of Democracy's Crisis

Acemoglu draws a direct and striking parallel between the dysfunction in AI development and the broader crisis of liberal democracy. In both domains, he argues, elite-driven escalation replaces deliberative, broadly beneficial progress .

The AI debate, he says, 'has a tendency to escalate everything,' driven by the same divide between an educated, credentialed elite and everyone else . Instead of democratically shaping AI to augment workers and serve public needs, the technology is being deployed to 'empower corporations and governments against workers and citizens' . The polarization and loss of trust in AI governance mirrors identical dynamics in political life .

Acemoglu has been a consistent critic of the current AI trajectory. He estimates that only about 5% of tasks will be profitably automated in the near term, yielding at most a 1–1.5% GDP increase, and that roughly 0.55% in total factor productivity gains is what AI will actually deliver over the next decade — a fraction of Wall Street's euphoric projections . The real problem, he argues, is not AI itself but the 'brainless' discourse and the concentration of power it enables .

The Solution: 'Working-Class Liberalism'

Acemoglu's proposed alternative is 'working-class liberalism' — a framework described in promotional material as a 'Roosevelt-like' project . Its core elements are:

• Rebuilding shared prosperity: Redirecting economic policy to benefit non-college workers through stronger bargaining power, better wages, and inclusive growth. This means moving away from an elite-focused agenda and toward one that delivers tangible gains for the least educated and least skilled .
• Democratic renovation: Revitalizing institutions of self-government and free expression so that liberalism again responds to popular demands rather than elite consensus. Acemoglu emphasizes self-government at the community level and rebuilding strong communities as essential to freedom .
• Technological redirection: Shaping AI and automation to augment human capabilities and empower workers, rather than replacing them or concentrating power in fewer hands. He calls for 'pro-worker AI' and a stronger safety net, including supporting AI tools that increase worker productivity and bargaining power rather than eliminate jobs .

Acemoglu frames this not as a return to mid-20th-century social democracy but as a new political philosophy that reclaims liberalism's original promise — broad freedom and shared prosperity — for a post-industrial, technologically disrupted world . He argues that 'repairing liberal democracy is not the answer' and that a fundamental remaking is required .
