Why Acemoglu Says College Credentials Became a Political Fault Line

Daron Acemoglu’s new book opens with a puzzle about what dominates American inequality debates. At a Washington meeting with left-leaning foundations, he expected non-college wage stagnation to be central. Instead, the conversation centered on gender, racial and sexual minority inequality—important topics, he writes, but not the aggregate driver of four decades of widening income gaps.

The MIT economist anchors the argument in a personal episode: a delayed flight and a bar conversation with a small-business owner with a very different education background. The encounter, he reflects, has become rare in an America where college-educated professionals increasingly live, socialize and work apart from people without degrees.

From that observation, Acemoglu builds a political diagnosis: the college-educated have grown more numerous and more influential, but also more insulated. Automation, offshoring and globalization have thinned good jobs for non-college workers, while the college-educated have formed a coalition with the tech sector that, in his telling, turned away from the economic priorities of the less educated.

The essay is excerpted from What Happened to Liberal Democracy: Remaking a Politics of Shared Prosperity, published by Dutton, an imprint of Penguin Random House.

What the Educational Segregation Argument Means for U.S. Politics

The airport-bar test and the empathy gap

Acemoglu’s central claim is not simply that Americans with and without college degrees earn different incomes, but that they now inhabit different social worlds. The airport anecdote operationalizes that distance: his professional peers, he suggests, would more readily converse with a foreign Ph.D. than an American high-school graduate. This is asserted, not measured—but it frames the rest of the argument.

The tech-professional coalition’s blind spots

In Acemoglu’s account, the political rise of the college-educated is tied to their economic rise. Automation, offshoring and globalization reduced the supply of good jobs for non-college workers, while professionals consolidated status. The result, he argues, is a coalition between segments of the college-educated and the tech sector that prioritizes cultural and global issues over the wage and employment conditions of workers without degrees.

What this means for left-leaning politics

The essay is explicitly directed at liberal foundations, civil servants and policymakers. The Washington meeting becomes a case study: a room filled with inequality-focused leaders did not foreground non-college wage stagnation. If that pattern holds, Acemoglu warns, well-educated liberal elites risk deviating from the economic coalition-building that once gave liberalism broad appeal.

For the Foundations and Civil Servants the Essay Confronts

The excerpt is a diagnostic challenge rather than a policy program, so its takeaways take the form of specific checks for the institutions it names.

  • For left-leaning foundations: Look at the agenda of your last inequality meeting. Did non-college wage stagnation and small-city/metropolitan divergence appear as named items, or were they absent as in the Washington discussion Acemoglu describes?
  • For policy staff and civil servants: Test whether your economic narrative would register with a high-school-educated small-business owner—the person at the center of Acemoglu’s airport-bar scene—rather than only with professional conference audiences.
