We Can’t Agree on Inequality—Here’s Why

Centuries of spirited debate have left us grappling with a perennial question: just how much economic inequality is tolerable? Unlike disparities rooted in race, gender, or disability—typically met with universal moral outrage—the discussion around economic inequality in income, consumption, and wealth remains a hotbed of contention. This very contestation is not a flaw but rather the essence of the debate.

This article provides a concise overview of the diverse opinions held by both the general public and experts regarding economic inequality, shedding light on the reasons why a clear-cut answer is so elusive. The stakes are undeniably high: while income disparities can incentivize innovation and stimulate economic growth, they can also entrench systemic disadvantages that inhibit opportunities regardless of individual effort. And this tension is just the tip of the iceberg.

Economic inequality—let’s call it simply “inequality”—emerges from a complex interplay of incentives, opportunities, institutions, luck, and personal choices. Some level of inequality is an inevitable byproduct of a vibrant market economy, while other aspects reflect entrenched barriers, discrimination, or inherited disadvantages. Additionally, it can arise from individuals pursuing distinct preferences and making varying trade-offs.

Take, for example, two otherwise identical individuals who are both free to make their own choices: one decides to work a 40-hour week, while the other opts for a 25-hour workweek to spend more time with family. Traditional measures of inequality—like Gini coefficients or interquintile ratios—would highlight an income disparity between these two. The question then arises: should this difference be categorized as a social issue, or is it merely the result of differing life choices?

Now consider the realm of entrepreneurship. Figures like Jeff Bezos and Sara Blakely amassed their fortunes because millions of consumers willingly purchased the products and services they provided. While it’s true that their wealth reflects the vast value they created, it also contributes to a growing income gap. The critical question remains: under what circumstances, if any, should such disparities be considered excessive?

Within corporate structures, another layer of complexity emerges: there seems to be a general consensus that a CEO should earn more than an entry-level employee. However, consensus quickly dissipates when we ask how much more. Is a 350-fold pay gap, as recent data suggests, justifiable? We see similar trends in sports and entertainment, where star athletes can earn significantly more than educators—not necessarily due to harder work but because global demand for their elite performances is vast and easily scalable. Inequality rises, yet so does the joy experienced by millions of fans. Again, the pressing question is whether such disparities should be deemed excessive.

Amidst this backdrop, public concern over inequality remains palpable and multifaceted. Surveys consistently reveal that a majority of Americans believe inequality is “too high,” yet less than half prioritize it as a pressing issue. Furthermore, perceptions of what constitutes “too high” vary sharply across political affiliations, income brackets, and personal experiences. Even among those who perceive inequality as excessive, there is a prevailing belief that some level of inequality is warranted. The challenge lies in defining what qualifies as “some,” and on this front, consensus is sorely lacking.

This divergence is not limited to the United States. A spring 2024 survey conducted by the Pew Research Center across 36 countries revealed that a median of 54 percent of adults consider economic inequality a “very big problem.” An additional 30 percent view it as a “moderately big problem,” while 16 percent dismiss it entirely. Individual perceptions are shaped by political ideology and income level, which further complicates the discourse about what level of inequality is acceptable. At a societal level, long-standing cultural narratives—from national myths of meritocracy to historical perspectives on social solidarity—ultimately shape what populations deem “fair.”

Even on a personal level, many individuals grapple with conflicting feelings. While they may feel uncomfortable about significant economic disparities, they also desire recognition for their efforts, talents, and calculated risks. Rewarding merit inevitably results in varying outcomes; thus, accepting the fruits of one’s labor means accepting that others may fare better—or worse.

International institutions echo this ambiguity. Goal 10 of the UN’s Sustainable Development Goals advocates for “reducing” inequality, as opposed to eradicating it entirely. In contrast, Goal 1—”No Poverty”—is an absolute directive. This distinction is telling: there is a broad consensus that poverty is intolerable, yet no agreement on the threshold of inequality that is too high.

Even prominent economists who champion the reduction of inequality shy away from defining a specific target. Anthony Atkinson remarked, “I am not seeking to eliminate all differences in economic outcomes. I am not aiming for total equality. Indeed, certain differences in economic rewards may be quite justifiable. Rather, the goal is to reduce inequality below its current level, in the belief that the present level of inequality is excessive.” Similarly, Joseph Stiglitz advocates for greater equality than what currently prevails in the United States, asserting, “We (or at least most of us) believe in equality—not complete equality, but far more than that characterized by today’s economy.” Yet, the terms “excessive” or “not complete equality” remain undefined. This lack of a concrete benchmark is not a trivial oversight; it underscores the intrinsic complexity of the issue.

Disagreement extends to philosophical discussions, where one might expect a more straightforward consensus to arise due to the abstract nature of the discourse, insulated from immediate policy implications. However, even philosophical analyses suggest that the absence of consensus is likely to persist.

A brief exploration of various philosophical perspectives illustrates that there is no universally accepted moral standard for distinguishing acceptable from unacceptable inequality. In fact, the more examples we examine, the clearer this point becomes. For instance, sufficientarians argue that everyone should have “enough,” yet the definition of “enough” remains nebulous. In developed nations, “enough” could mean basic nutritional needs are met or the ability to engage fully in contemporary life—which may encompass access to broadband, transportation, and higher education. Moreover, human diversity complicates any simple delineation: what suffices for one may not suffice for another. This challenge resonates across many philosophical frameworks.

Limitarians assert that possessing “too much” is morally objectionable and that justice may necessitate upper limits on wealth. However, they too grapple with defining what constitutes “too much.” Limitarians struggle to establish non-arbitrary thresholds that differentiate between legitimate rewards and excessive accumulation. Consider again Bezos and Blakely: their wealth, while a product of genuine innovation, also starkly highlights inequality. This duality makes it challenging to ascertain where justified reward ends and excessive accumulation begins.

Utilitarianism posits that inequality is morally permissible if it maximizes overall utility. In its act form, this theory evaluates distributions based solely on their impact on total welfare, rather than through the lens of an independent fairness standard. A well-known critique—the “utility monster” thought experiment—reveals a striking implication of this commitment: if one individual could derive significantly more utility from resources than others, maximizing total utility could justify allocating a disproportionate share to that individual. Although these scenarios are deliberately extreme, they highlight a structural feature of act utilitarianism: it can, in theory, endorse significant inequalities whenever these enhance overall utility, even at the expense of fairness or proportionality. Rule utilitarianism attempts to mitigate this issue by shifting focus from individual actions to overarching rules that maximize welfare, thereby curbing outcomes that could undermine social trust and stability. However, this approach introduces its own challenges. It may necessitate adherence to rules even when breaking them would yield better results, leading to the familiar critique of “rule worship.” More fundamentally, rule utilitarianism can become unstable: rigid rule-following risks failing to maximize utility in specific instances, while permitting exceptions whenever they would enhance utility ultimately collapses back into act utilitarianism, losing its distinctiveness.

Rawlsians focus on maximizing the position of the least advantaged, as measured by their access to social primary goods—rights, liberties, opportunities, income, and wealth. Yet, translating this principle into effective policy aimed at addressing inequality is far from straightforward. Identifying the least advantaged group, quantifying primary goods, and determining whether a given inequality genuinely enhances the long-term prospects of the disadvantaged pose significant empirical and institutional challenges.

Desert-based and meritocratic theories seek to justify inequality through different lenses, both of which face critiques tied to their rationales. Desertism emphasizes rewarding individuals for outcomes they can be held accountable for, yet establishing responsibility is often fraught with difficulty—outcomes can hinge on luck, social context, and other factors beyond personal control. Meritocracy, on the other hand, values talent, natural ability, or recognized achievements, even when much of this stems from chance—making it susceptible to criticism for perpetuating unearned advantages. This dichotomy is illustrated by beauty pageants: a winner may merit her title for her exceptional appearance, yet since that beauty is largely inherited rather than earned, she may not truly deserve the accolade under a justice framework sensitive to responsibility.

Luck Egalitarians differentiate between “brute luck” (circumstances beyond an individual’s control) and “option luck” (choices with uncertain outcomes). Within this framework, opinions on whether society should mitigate the consequences of option luck remain deeply divided. Nevertheless, there is broad consensus on the need to address the ramifications of brute luck—though defining what constitutes brute luck can be challenging in practice (consider, for instance, family background).

Strict egalitarians advocate for near-equal outcomes. This stance is exemplified by Peter Singer, who asserts that “the principle of the equality of human beings is not a description of an alleged actual equality among humans; it is a prescription for how we should treat human beings.” The normative criterion of strict egalitarianism posits that a uniform distribution of resources represents the most authentic realization of its moral ideal. However, this perspective faces widespread criticism for its potential to undermine the incentives driving economic vitality. Imposing a near-equal distribution of outcomes post-factum distorts pre-emptive behavior: severing the link between effort and reward may lead individuals to complacency. By removing penalties for low productivity, such a system risks creating a dependency trap that diminishes the motivation to innovate. Furthermore, recipients of extensive state assistance—by virtue of the system’s design—may become passive citizens, prone to social isolation and a sense of detachment from their nation’s political and socioeconomic life.

Each of these frameworks captures valuable insights and is subject to legitimate criticisms. Yet, none of these theories provide a clear, uncontested policy benchmark for the acceptable level of inequality. The divergence lies not only in why inequality might be deemed acceptable but also in how much inequality is justifiable. Absent shared moral foundations, achieving a stable and principled consensus on the “correct” level of inequality remains a distant goal.

This predicament leaves us in a curious state. We can measure inequality with precision, analyze its causes, and design interventions aimed at enhancing mobility and opportunity. Yet, we lack a yardstick for discerning when inequality becomes problematic. Strikingly, we may never possess one.

This absence carries significant implications. Without normative anchors, discussions risk devolving into circular arguments: inequality is “too much” simply because it exceeds an unspecified standard. But what standard? Until we resolve this question, rhetoric often outpaces reason.

Ultimately, the core challenge lies not in quantifying inequality but in justifying both its origins and its allowable extent within a free and prosperous society. On this critical question, consensus remains elusive—and in a pluralistic world filled with diverse agents, perhaps that is as it should be.
