Rising inequality is not just an economic problem. It is an institutional legitimacy problem — the condition that makes institutions whose benefits accrue primarily to the already-advantaged increasingly difficult to defend.
The Legitimacy Mechanism
The relationship between economic inequality and institutional legitimacy operates through a specific mechanism: institutions whose rules, outcomes, and access patterns systematically advantage the already-advantaged lose the legitimacy of the populations who observe this pattern and conclude that the institutions are not neutral frameworks for collective governance but instruments of the advantaged interests they serve. This conclusion is not necessarily wrong. The tax system that allows the highest earners to pay lower effective rates than median earners, the regulatory system that is shaped by the industries it regulates, the criminal justice system that incarcerates the poor at rates that reflect poverty rather than crime, and the political system that is more responsive to donor interests than to median voter preferences are all institutions whose distributional outcomes reflect the power asymmetries that produced and maintain them.
The legitimacy consequence of this pattern is the democratic disengagement, the institutional distrust, and the political volatility that characterise societies with high and rising inequality. The populations most disadvantaged by the existing institutional arrangements are the populations whose political disengagement and institutional distrust are highest — which reduces their capacity to change the arrangements that disadvantage them. The populations most advantaged by the existing arrangements have both the strongest interest in maintaining them and the political capacity to do so. The result is the self-reinforcing institutional equilibrium in which rising inequality produces the institutional conditions that maintain rising inequality.
Inequality is an institutional legitimacy problem because it reveals whose interests the institutions are actually serving. The institution that produces systematically unequal outcomes is not a neutral framework that has produced unequal results by accident — it is a framework whose design and governance reflect the power of the actors who shaped it. Addressing inequality requires addressing the institutional power that produces it, which is a harder political task than addressing the inequality symptoms.
