Why are societies stratified, and is inequality necessary? Three theoretical traditions dominate the sociological answer. The structural-functionalists treat stratification as a functional necessity that motivates talent; the Marxists treat it as exploitation rooted in the ownership of productive property; and the Weberians offer a pluralist, multidimensional account in which economic class is only one axis of advantage. A strong Paper I answer sets these in dialogue rather than treating them in isolation.

The functionalist theory: Davis and Moore

In their 1945 essay Some Principles of Stratification, Kingsley Davis and Wilbert Moore argued that stratification is universal, inevitable and functionally necessary. Every society faces the problem of allocating individuals to social positions and motivating them to perform the associated duties. Some positions are functionally more important and require scarce talent and long, costly training. To ensure that the most able persons undergo this sacrifice and conscientiously fill demanding roles, society must attach differential rewards — income, prestige and privilege — to them. Inequality is thus an unconsciously evolved device by which societies guarantee that the most important positions are filled by the most qualified.

The core propositions are that positions differ in functional importance, that talent is scarce, that training entails sacrifice, and that unequal rewards are the incentive that resolves the allocation problem. Stratification, on this view, is not merely inevitable but positively beneficial for social order and efficiency.

Tumin's critique

Melvin Tumin offered the classic rebuttal in 1953. He challenged nearly every premise. First, functional importance is impossible to measure objectively — are engineers really more important than the sanitation workers whose absence would halt a city? Second, the theory assumes a limited pool of talent, yet stratification itself restricts the discovery of talent by denying training and opportunity to subordinate groups, so ability goes unrecognised. Third, training is not always a sacrifice; students enjoy leisure, deferred responsibility and psychic rewards, and the costs are often borne by parents. Fourth, differential reward is not the only motivator — intrinsic satisfaction and social duty also drive performance. Above all, Tumin argued that stratification is dysfunctional: it limits mobility, entrenches privilege, distributes unequal senses of self-worth, and provokes hostility that threatens integration rather than securing it. Stratification, far from being a neutral escalator of talent, is a mechanism for perpetuating the advantages of those already on top.

The Marxist theory

For Karl Marx, stratification is neither functional nor inevitable but a historical product of the relations of production. In every class society the fundamental division is between those who own the means of production and those who, owning only their labour power, must sell it to survive. Under capitalism these are the bourgeoisie and the proletariat. Class is defined objectively by one's relationship to productive property, not by income or status.

The relationship is one of exploitation: the worker produces value beyond the cost of their wages, and this surplus value is appropriated by the capitalist as profit. Stratification is therefore a relation of domination sustained by an economic base and reinforced by a superstructure of law, politics and ideology. The dominant ideas of an age are the ideas of the ruling class, generating false consciousness that masks exploitation. Marx anticipated the polarisation of classes, the immiseration of the proletariat, and the transformation of a class-in-itself into a class-for-itself — a self-conscious revolutionary agent that would overthrow capitalism and inaugurate a classless society. Critics note that his prediction of polarisation underestimated the growth of the middle classes and the resilience of capitalism, but his insistence on the material roots of inequality remains foundational.

Weber's multidimensional model

Max Weber accepted much of Marx's economic analysis but rejected its reductionism. In Economy and Society he distinguished three analytically separate dimensions of stratification: class, status and party.

  • Class is an economic phenomenon rooted in market situation — the life-chances a person's marketable skills, property and services command in the marketplace. Weber recognised a plurality of classes (property, commercial, social) rather than a simple two-fold split, allowing for the propertyless yet skilled professional.
  • Status (Stände) is the social estimation of honour, expressed through distinct styles of life, consumption patterns, commensality and social closure. Status groups, unlike classes, are communities conscious of themselves; caste is the extreme case of a closed status order.
  • Party concerns the acquisition of power — organisations, whether political parties, unions or pressure groups, that pursue influence within an association.

Crucially, these dimensions can diverge: a wealthy but stigmatised trader may enjoy high class but low status, while an impoverished aristocrat retains honour without means. Weber thus opened stratification to a pluralist analysis of overlapping and cross-cutting hierarchies, a framework indispensable for understanding modern societies where class, prestige and political power do not neatly coincide.

How to use this in the exam

  • Structure comparatively. Present functionalist, Marxist and Weberian theories as answers to a single question — the origin and function of inequality — so the essay reads as an argument, not a list.
  • Always pair Davis–Moore with Tumin; a functionalist answer without the critique looks incomplete, and Tumin's points on measuring functional importance are the highest-yield material.
  • On Marx, foreground the concepts — means of production, surplus value, exploitation, false consciousness, class-for-itself — and acknowledge the middle-class critique to show balance.
  • Use Weber to transcend Marx: the class–status–party triad, market situation and the possibility of divergent hierarchies are the analytical payoff. This directly grounds the next note on the dimensions of stratification.
  • Conclude with synthesis: contemporary sociologists such as Erik Olin Wright and Frank Parkin blend Marxian and Weberian insights, a point that signals wider reading and lifts the grade.
