Why Socio-Economic Class Is Not a Protected Characteristic in Discrimination Law

The exclusion of socio-economic status (social class) from the list of protected characteristics in most anti-discrimination law frameworks is the result of a complex interaction of definitional, ideological, political, legal-structural, and historical factors. The question is not merely a doctrinal curiosity — it strikes at the heart of what anti-discrimination law is designed to achieve and whom it is meant to protect.

1. Definitional and Categorical Instability

A fundamental requirement for any protected characteristic in a grounds-based system is that it must possess "some definitional and categorical stability" [1]. The protected characteristics currently recognised — such as race, sex, disability, and age — must be sufficiently stable categories to allow courts and tribunals to apply the law in a consistent and predictable manner. Socio-economic status, however, is an inherently fluid and multi-dimensional concept. It encompasses income, occupation, education, housing status, wealth, and social background, none of which has a clear or stable boundary [1]. As Ganty notes, "social condition" is "in itself a rather broad and vague concept" that has "barely received definitions or applications at national, international and European level" [3]. This conceptual ambiguity makes it difficult for legal systems to operationalise socio-economic status as a judicially manageable standard.

Moreover, there is a deeper philosophical challenge: unlike race or sex, socio-economic status is not typically viewed as an inherent or immutable characteristic of the person. Atrey explains that this has been a persistent barrier — poverty and its attendant deprivations are often seen as "not an autonomous choice, but rather a multifaceted situation from which it may be difficult, if not impossible, to escape without assistance" [6]. Yet courts have historically treated socio-economic status as more mutable and therefore less deserving of protection, relying on the assumption that individuals bear some responsibility for their economic circumstances [3]. This perception persists even though the immutability test has been steadily eroded for other protected characteristics, such as religion (which is clearly a matter of choice) and gender reassignment (which is defined precisely by its mutability) [1].

2. The Ideological Resistance: Individual Responsibility versus Structural Inequality

Perhaps the most powerful barrier to including socio-economic class as a protected characteristic is ideological. Discrimination law in Western liberal democracies is built on a model of formal equality — the idea that individuals should be treated alike regardless of certain irrelevant characteristics. This model fits comfortably with a market-based liberal ideology that views some degree of economic inequality as inevitable or even desirable [1]. As Malleson explains in her analysis of UK law, "It has become increasingly accepted in all the main political parties in Britain since the 1980s that in a competitive capitalist society some degree of economic inequality is inevitable or even desirable. Poverty is now more likely to be seen as the result of life choices rather than bad luck or structural injustice" [1].

This ideological position sharply distinguishes socio-economic disadvantage from other forms of discrimination. Discrimination based on race, sex, or disability can be framed as irrational prejudice — a departure from the meritocratic ideal. But addressing socio-economic inequality directly challenges the foundational premises of capitalist economic organisation. As Malleson observes, "Addressing disadvantage arising from SES through equality legislation potentially challenges this ideological perspective and raises the prospect of exposing the structural injustices which give rise to SES inequality in the first place" [1]. In contrast, the existing protected characteristics can more easily be kept "narrowly focused on individual treatment as both the evidence and the substance of discrimination" [1].

Collins makes a related point: the concept of social inclusion, which has underpinned many anti-discrimination law reforms, does not seek equality of outcomes but rather a minimum level of welfare for every citizen [2]. This "Third Way" approach allows governments to address the most extreme forms of social exclusion without embracing the egalitarian agenda that recognising class as a protected ground would imply.

3. Political Will and the Historical Contingency of Protected Characteristics

The list of protected characteristics in any jurisdiction is not the product of abstract philosophical reasoning but of political struggle. Malleson notes that the Equality Act 2010 in the UK, like the anti-discrimination legislation it superseded, was "not the 'gift of enlightened rulers' but the outcome of struggles between different interest groups" [1]. Each characteristic that has been added to the list — from race and sex to religion, sexual orientation, and gender reassignment — required sufficient political mobilisation to generate the leverage necessary for inclusion.

Socio-economically disadvantaged groups, however, face unique obstacles to political mobilisation. Ganty highlights that "people in precarious situations are often ashamed of their position and feel responsible for it. The stereotypes and prejudice they are victims of reinforce the feeling of being inferior, worthless and lazy" [3]. This leads to a "non-take-up phenomenon" — disadvantaged individuals avoid claiming rights or identifying as part of a group that suffers discrimination [3]. The very heterogeneity of the category — "socio-economically underprivileged people is very heterogeneous culturally and socially speaking" [3] — makes collective identity formation and political mobilisation exceptionally difficult.

In the UK, Section 1 of the Equality Act 2010, which would have imposed a duty on public authorities to have due regard to reducing socio-economic inequalities, was passed in the last days of the Labour Government but was never implemented by the incoming Conservative-Liberal Democrat coalition. The then Home Secretary, Theresa May, argued that it would be "just another bureaucratic box to be ticked" [1]. As Malleson notes, the timing was revealing: "When Theresa May announced the scrapping of section 1 of the EA 2010, she drew attention to proposed legislation to allow men convicted of consensual sex with men over 16 before the law was changed in 1967 to apply to have those convictions overturned. By focusing on historical discrimination against a sub-set of gay men the government arguably sought to demonstrate a commitment to individual anti-discrimination measures while rejecting the need for a legislative response to ongoing socio-economic group-based inequality" [1].

4. The Anticlassification versus Antisubordination Debate

The very structure of anti-discrimination law reflects a deep jurisprudential divide between two conceptions of equality. The "anticlassification" principle holds that the government may not classify people on the basis of forbidden categories like race or sex. The "antisubordination" principle, by contrast, holds that law should reform institutions and practices that enforce the secondary social status of historically oppressed groups [5]. Balkin and Siegel argue that American civil rights jurisprudence has never fully embraced the antisubordination principle [5]. This matters directly for class, because addressing socio-economic disadvantage — as opposed to simply prohibiting certain forms of classification — inevitably requires an antisubordination approach that asks whether state action perpetuates group-based subordination.

As Balkin and Siegel explain, the anticlassification principle is not self-implementing: it requires a host of subsidiary implementation decisions (e.g., what counts as a classification, what scienter standard applies, what spheres of life are covered) that courts decide inconsistently, often guided implicitly by antisubordination values [5]. But the dominant legal framework remains one in which discrimination is conceptualised as the intentional act of a biased perpetrator, not as structural disadvantage [8]. This "perpetrator perspective" (as Freeman termed it) is fundamentally ill-suited to addressing socio-economic inequality, which is primarily a product of structural economic forces rather than individual acts of prejudice.

5. The Nature of Socio-Economic Disadvantage: Redistribution versus Recognition

Atrey provides a powerful analysis of why poverty has remained "largely unfamiliar to discrimination law" [6]. She argues that the intersectional nature of poverty — which is composed of multiple, cross-cutting disadvantages (joblessness, homelessness, malnutrition, illiteracy, stigma, social exclusion) that intersect with other grounds like race, gender, and disability — makes it a paradigmatic case for discrimination law, yet it is systematically excluded [6].

The root of the difficulty lies in the traditional division of labour between two domains of law and policy. As Goldblatt explains, poverty has historically been treated as a matter of "redistribution" to be addressed through welfare state mechanisms and socio-economic rights, while discrimination law has focused on "recognition" — combating stigma, prejudice, and stereotyping [4]. This dichotomy, however, is misleading. Goldblatt notes that the UN Committee on Economic, Social and Cultural Rights has explicitly recognised that "a person's social and economic situation when living in poverty or being homeless may result in pervasive discrimination, stigmatization and negative stereotyping which can lead to the refusal of, or unequal access to, the same quality of education and health care as others" [4].

The failure to appreciate this intersectional character of poverty leads courts to systematically misconceive discrimination claims involving socio-economic disadvantage. Atrey demonstrates through comparative case law that courts routinely treat poverty as "severed from its constitutive disadvantages" [6], as in the Indian Supreme Court's decision in Rajbala v State of Haryana, where the court upheld educational and sanitation requirements for election candidates despite evidence that these would disqualify over 50% of the rural poor, especially women and lower castes [6]. Similarly, in the Canadian case Gosselin v Quebec, the Supreme Court treated Louise Gosselin's compounding struggles with destitution, homelessness, and mental health issues as "personal problems" rather than as evidence of structural discrimination [6].

6. The Economic Logic of Class Discrimination in Practice

The exclusion of class from protection is also reinforced by the perceived economic rationality of class-based discrimination. Ashley and Empson's study of leading London law firms found that discrimination on the basis of social class is "perceived as a rational commercial strategy by law firms wishing to charge the very highest fees" [7]. In knowledge-intensive firms where the quality of work is inherently ambiguous, presentation of an "upmarket" image becomes a proxy for quality. This is achieved by recruiting graduates with specific forms of cultural capital — accent, dress, mannerisms, and attendance at elite universities — which are unequally distributed along class lines [7]. The authors conclude that "doing otherwise represents a perceived risk to their image and brand" [7].

This finding has profound implications. It suggests that class-based discrimination is not merely the result of irrational prejudice (as race or sex discrimination is typically understood) but is deeply embedded in the business model of elite professional services. This makes it far more resistant to the standard toolkit of anti-discrimination law, which assumes that discrimination is an irrational departure from market efficiency.

7. The Structural Limitations of Grounds-Based Frameworks

Even if there were political will to include socio-economic status as a protected characteristic, the grounds-based framework itself may be a poor vehicle for addressing class inequality. Collins argues that anti-discrimination law, as conventionally conceived, addresses the recognition and status dimensions of inequality — combating stigma, stereotyping, and exclusion — rather than distributive inequality itself [2]. Including socio-economic status as a ground would primarily serve the purpose of "addressing the stigma, prejudice and social exclusion arising from poverty" rather than addressing poverty itself [1]. As Malleson notes, "tacking a ground rooted in distributive inequality onto the traditional identity-based grounds can only ever have a marginal effect on substantive socio-economic inequality. Indeed, it might even be seen as worse than not including SES in the protected characteristics at all since it is based on the premise that poverty, like gender, race or sexual orientation, is a characteristic which we should respect rather than eradicate" [1].

This raises a fundamental question: is the goal to protect poor people from discriminatory treatment, or to eliminate poverty? Anti-discrimination law is structurally designed for the former, not the latter. This may explain why, even in jurisdictions that have taken tentative steps to include some class-related grounds — such as "source of income" in some Canadian provinces or "social condition" in Quebec — the impact has been limited [3].

8. The Paradox: Class as the Most Significant but Least Protected Axis of Inequality

A striking paradox emerges from the literature. Malleson argues that "socio-economic status (SES) remains outside the protected characteristics, despite the fact that it is arguably the most pervasive and fast-growing axis of inequality in the UK today" [1]. In a powerful passage, she notes: "A key justification for the use of protected characteristics in the anti-discrimination law framework, despite the fact that they are relatively crude and imperfect, is that just a few facts are determinative of a great deal about a person's life chances. In the UK today the most determinative fact in relation to most people's life chances is their socio-economic origin and status" [1].

Malleson further argues that the relationship between the protected characteristics and people's lived experience of inequality has weakened over time. Thirty years ago, being a woman, black, disabled, or openly gay was often enough on its own to radically damage a person's life chances. Today, while these characteristics can still have significant negative impacts, they "have become less and less determinative of people's life chances in the absence of SES disadvantage" [1]. Yet the law continues to focus on the former while excluding the latter.

This paradox may not be accidental. Malleson suggests a cynical interpretation: "the process of expansion and fragmentation can serve useful political purposes. Just as the focus on race in the US masks the significance of class, so the emphasis in the UK on a wider range of narrower protected characteristics, such as sub-categories of sexual orientation, can deflect attention from the bigger and more intractable problem of the widening gap in equality outcomes between different socio-economic groups" [1].

Conclusion

Socio-economic class is not a protected characteristic in discrimination law because of a confluence of factors: its definitional instability and perceived mutability; the ideological preference for treating economic inequality as an inevitable or desirable feature of market societies; the historical contingency of protected characteristics on successful political mobilisation by groups that the poor are uniquely ill-equipped to mount; the dominance of an anticlassification framework ill-suited to addressing structural disadvantage; the conceptual separation of redistribution from recognition; the perceived economic rationality of class-based discrimination; and structural limitations of the grounds-based model itself. The consequence is that anti-discrimination law, as currently configured, bypasses what may be the most pervasive and damaging axis of inequality in contemporary societies.
