Theories of stratification: functionalist, Marxist, Weberian#

Marxist versus Weberian stratification

Fig. 1Marxism reduces stratification to class; Weber adds status and party as cross-cutting dimensions.

Functionalist theory, in the classic statement of Davis and Moore, explains stratification as necessary and beneficial for society. Because some social positions are functionally more important and require scarce talent and prolonged training, society must attach greater rewards - income, status, power - to them in order to motivate the most able people to make the sacrifices needed to fill them. Stratification, on this view, is a mechanism of effective 'role allocation': it ensures that the most important roles are conscientiously performed by the most capable, and unequal rewards are the incentive that makes this work. Stratification is thus a functional response to the needs of any complex society.

The functionalist theory has been heavily criticised, and evaluating it is a core exam task. Tumin's classic critique asks how we can know which positions are 'functionally most important' independently of the rewards they already receive, argues that stratification actually wastes talent by denying opportunity to the disadvantaged, and notes that inequality of outcome undermines the equality of opportunity a meritocracy requires. The theory also cannot explain why inherited wealth and discrimination sever the link between reward and function, and it assumes a value consensus over rewards that conflict theorists deny. These criticisms make the functionalist account, while capturing the incentive function of reward, difficult to sustain as a full explanation.

Marxist theory explains stratification as class exploitation rather than functional necessity. Society is divided fundamentally into two classes defined by their relationship to the means of production - the bourgeoisie who own them and the proletariat who sell their labour - and the wealth and privilege of the former derive from the surplus value extracted from the latter. Stratification is therefore not a benign incentive system but the institutionalised expression of exploitation, reproduced through ideology that legitimates inequality and produces false consciousness. Marx predicted the polarisation of the classes and eventual revolution, though critics note this has not occurred and that the model struggles with the complexity of the modern class structure.

Weberian theory offers a more multi-dimensional account that many find the most realistic. Weber accepted the importance of economic class - defined by market position and life chances - but argued that stratification also operates through 'status' (social honour or prestige, which does not always track economic class) and 'party' (organised power). These three dimensions can cross-cut: a group may have high status but low economic class, or vice versa. This pluralistic model captures inequalities (such as those of status groups) that a single-cause Marxist model misses, and it underpins much contemporary analysis of class, though critics argue it describes multiple hierarchies without a driving explanation of why they arise. Evaluating stratification therefore means weighing the functionalist incentive account, the Marxist exploitation account and the Weberian multi-dimensional account against one another and against the evidence.

Davis and Moore: the functionalist logic

Worked example

Model essay plan: the functionalist theory of stratification

Plan a 20-mark answer evaluating the functionalist theory of stratification.

Set up the debate
Functionalists (Davis & Moore) say stratification is a functional necessity; Marxists and Weberians disagree. Signal a judgement. Hook to the Item.
Develop functionalism
Unequal rewards motivate the ablest to fill the most important roles - stratification as effective role allocation in a meritocracy.
Critique it (Tumin)
How is 'importance' judged apart from reward? Inheritance and discrimination break the link; inequality of outcome undermines equal opportunity; consensus is assumed.
The conflict alternatives
Marxism: stratification is exploitation reproduced by ideology. Weber: multiple cross-cutting dimensions (class, status, party) that functionalism collapses into one.
Judgement
Conclude that the incentive argument has limited force but cannot explain inherited privilege or the scale of inequality, so conflict and Weberian accounts are more convincing.

Result: A top-band plan credits the incentive logic, dismantles it with Tumin's critique, sets Marxist and Weberian accounts against it, and judges the functionalist theory inadequate as a full explanation of stratification.

Typical mistakes

Describing the theories in turn without comparing or evaluating them.
Missing the distinctiveness of the Weberian model - status and party are not reducible to economic class.

The New Right, feminist and postmodern views#

Theories of stratification

Fig. 3The full range of stratification theories - the newer perspectives complicate the debate over whether class still matters.

The New Right view of stratification shares the functionalist belief that inequality is beneficial but grounds it in the virtues of the free market rather than in society's functional needs. Saunders argues that inequality is desirable because it provides incentives that drive effort, enterprise and economic growth, and that attempts to impose equality of outcome are both unjust (penalising talent and effort) and economically damaging. The New Right therefore defends inequality as the price and product of a dynamic market society, and, through the underclass thesis, blames welfare for undermining the incentives on which prosperity depends - a position examined further in the section on the changing class structure.

Feminist theories argue that the classic theories of stratification are 'gender-blind', treating class as the master category and neglecting the systematic inequality between men and women. Feminists analyse patriarchy as a structure of stratification in its own right, in which men as a group hold advantages in income, occupational power, status and control within the household. They also criticise the conventional practice of allocating women to a class on the basis of their husband's or father's occupation, arguing that this hides women's own distinct position. The feminist contribution is to insist that any adequate theory of stratification must treat gender as a dimension of inequality alongside, and intersecting with, class.

Postmodern theories challenge the whole enterprise of stratification theory. They argue that in a fragmented, diverse and consumption-oriented society, the large, stable classes of the industrial era have broken up, and that identity is now based on consumption and lifestyle rather than on a fixed structural position. Class, on this view, has lost its power to shape identity and action, and the grand theories that made class central - Marxism above all - no longer fit. Some postmodernists therefore doubt that 'class' remains a useful concept at all, emphasising instead the proliferation of fluid, individualised identities.

Evaluating these newer perspectives sharpens the topic's central debate about whether class still matters. The New Right captures the incentive function of inequality but is criticised for ignoring inherited advantage and the structural causes of poverty. Feminism corrects the gender-blindness of the older theories but is itself internally divided over the relationship between gender and class. Postmodernism identifies real cultural changes - the decline of old class communities, the rise of consumption-based identity - but is strongly criticised for ignoring the persistence of class inequalities in life chances, which remain well documented. The strongest answers use these perspectives to complicate, rather than dismiss, the analysis of class, and reach a judgement that class continues to matter even as its form and cultural expression change.

Worked example

Evaluating the postmodern 'death of class'

Assess the postmodern view that class is no longer an important form of stratification.

State the claim
Postmodernists argue stable classes have fragmented and identity is now based on consumption and lifestyle, so class has lost its structuring power.
Credit the insight
The decline of old class communities and the rise of consumption-based identity are real changes the claim captures.
Apply the evidence critique
But class inequalities in income, health, education and life chances persist and are well documented - class still shapes life chances even where it is less named.
Judgement
Conclude that class has changed in form and cultural expression but has not lost its importance, so the 'death of class' thesis is overstated.

Result: Class has changed in form and cultural expression but continues to shape life chances, so the postmodern 'death of class' thesis is overstated - class remains an important form of stratification.

Typical mistakes

Equating the New Right with functionalism without noting its distinctive market emphasis.
Accepting the postmodern 'death of class' thesis without the evidence that class still shapes life chances.

The dimensions of inequality: class, status and power#

StandardAQA 7192/2 Stratification and DifferentiationDfE GCE Sociology subject content

Weber's three dimensions of inequality

Fig. 4Weber analysed inequality along three cross-cutting dimensions - class, status and party (power).

Following Weber, sociologists analyse inequality along three related but distinct dimensions - class, status and power - and the topic requires an understanding of each and of the problems of defining and measuring them. Class refers to economic position: a person's relationship to the means of production (Marx) or their market situation and life chances (Weber). Status refers to social honour or prestige - the esteem in which a position or group is held, expressed through lifestyle, consumption and social acceptance. Power refers to the capacity to achieve one's aims, including organised power through 'party'. Because these dimensions can cross-cut, a full picture of a person's position requires attention to all three.

Defining and measuring class is notoriously difficult, and this is an examinable issue in its own right. Occupation is the usual proxy for class in official and sociological schemes, but it raises problems: how to classify the wealthy who do not work, the unemployed, students and retired people; how to allocate class within households, which feminists criticise when women are classified by a male 'head'; and how to capture wealth (as opposed to income) and the very top and bottom of the structure. The scheme used shapes the picture of inequality produced, so measurement is not a neutral technicality but affects what inequalities become visible.

Status and power add dimensions that a purely economic measure of class misses. Status groups - based on ethnicity, lifestyle, occupation or other sources of honour - may not coincide with economic class, so that a group can have high status and modest economic resources, or great wealth but low status. Power, analysed through pluralist, elite and Marxist accounts, is distributed in ways that both reflect and shape class and status. Recognising these dimensions guards against reducing all inequality to income and connects the topic to the analysis of power in the core theme.

The interplay of the dimensions is central to evaluation. Marxists argue that class (economic position) is fundamental and that status and power ultimately derive from it; Weberians argue that the three dimensions are analytically independent and can vary separately, giving a more complex and, many argue, more realistic map of inequality. Contemporary analysis often combines economic, status and cultural dimensions - some drawing on Bourdieu's forms of capital (economic, cultural, social) to capture how advantage is transmitted. Evaluating the dimensions means weighing the Marxist claim of the primacy of class against the Weberian and Bourdieusian emphasis on multiple, interacting dimensions, and reaching a judgement about how best to map inequality - while treating any classification as a construction with consequences.

Worked example

Explaining problems of measuring class

Explain two problems sociologists face in defining and measuring social class.

Problem one: occupation as a proxy
Occupation is the usual measure, but it cannot easily classify the wealthy who do not work, the unemployed, students or the retired, distorting the picture of inequality.
Develop
It also captures income more than wealth, so the concentration of assets at the top - central to inequality - is understated.
Problem two: the household
Allocating class within households (traditionally by a male 'head') hides women's own position, a practice feminists criticise as gender-blind.
Develop
Note that the scheme chosen shapes the inequalities that become visible, so measurement is a construction, not a neutral technicality.

Result: Two problems - the limits of occupation as a proxy (missing the workless and wealth) and the household allocation that hides women's position - show that measuring class is a consequential construction, not a neutral technical exercise.

Typical mistakes

Reducing all inequality to economic class and ignoring status and power as distinct dimensions.
Treating occupational class schemes as neutral measures rather than constructions with consequences.

The changing class structure and the underclass#

AdvancedAQA 7192/2 Stratification and DifferentiationDfE GCE Sociology subject content

Illustrative relative social mobility by class origin

Fig. 5Typical illustrative pattern (not official statistics): class of origin still strongly predicts class of destination - relative mobility remains limited.

The class structure has changed markedly since the classic theories were formulated, and analysing this change is central to the topic. The most striking shift has been the decline of the traditional manual working class - shrunk by deindustrialisation and the loss of manufacturing employment - and the growth of a large service and professional 'middle class' or 'service class'. Sociologists debate how to interpret this: whether it represents the 'embourgeoisement' of the workers (their absorption into the middle class), the fragmentation of a once-unified working class, or simply a change in the occupations through which class inequality operates. The point is that the shape of the class structure is not fixed but historically variable.

The upper class and the growth of a wealthy elite are analysed alongside the middle and working classes. Sociologists study how the upper class reproduces its advantage across generations through wealth, elite education and social networks (social closure), and debate the emergence of a 'transnational' or 'super-rich' global elite. The persistence and, on some measures, the growth of concentration at the top challenge the postmodern claim that class has dissolved, and connect the topic to the analysis of wealth, power and life chances.

The underclass debate is the topic's most contested area. The New Right, notably Murray, argues that below the working class there has emerged an 'underclass' - a group characterised by welfare dependency, family breakdown, detachment from work and distinctive values that reproduce their own poverty and generate social problems - and that an over-generous welfare state has created it. Critics reject the concept as a cultural, victim-blaming label that stigmatises the poor, argue that there is little evidence for a distinct self-perpetuating culture, and offer instead structural accounts in which the 'underclass' is simply the most disadvantaged section of the working class, produced by the labour market and welfare, not by their own values.

Evaluating the changing class structure and the underclass means weighing these interpretations against the evidence and connecting them to the theories. The decline of the manual working class and the growth of the service class are real, but do not amount to the disappearance of class inequality; the concentration of wealth at the top persists; and the underclass thesis, while politically influential, is widely criticised as a cultural mislabelling of structural disadvantage. The strongest answers show that the class structure has been reshaped rather than dissolved, reject the cultural underclass thesis in favour of a structural account, and reach a judgement that class inequality endures in changed forms - presenting any figures as broad patterns rather than precise statistics.

Worked example

Model essay plan: has an underclass emerged?

Plan a 20-mark answer evaluating the view that an underclass has emerged.

Set up the debate
The New Right claims an underclass has emerged; structural critics reject the concept. Signal a judgement. Hook to the Item.
The New Right case
Murray: a group defined by welfare dependency, family breakdown and detachment from work, whose values reproduce poverty, created by generous welfare.
Critique it
A cultural, victim-blaming label; weak evidence for a distinct self-perpetuating culture; in-work poverty shows the poor are not simply work-averse.
The structural alternative
The 'underclass' is the most disadvantaged section of the working class, produced by the labour market and welfare, not by its own values.
Judgement
Conclude that severe disadvantage exists but is best explained structurally, not as a distinct cultural underclass - so the underclass thesis is rejected.

Result: A top-band plan develops the underclass thesis, dismantles it with the victim-blaming and in-work-poverty critiques, offers a structural account of the most disadvantaged, and judges the cultural underclass concept unsupported.

Typical mistakes

Accepting the New Right underclass thesis uncritically as description rather than a contested, victim-blaming concept.
Treating the decline of the manual working class as the disappearance of class inequality.

Social mobility and life chances#

StandardAQA 7192/2 Stratification and DifferentiationDfE GCE Sociology subject content

Absolute versus relative mobility

Fig. 6Absolute mobility (total movement) can be high while relative mobility (comparative chances by origin) stays low - the key to assessing openness.

Social mobility - movement between positions in the stratification system - is a key measure of how open or closed a society is, and the topic requires an understanding of its patterns and significance. Sociologists distinguish intergenerational mobility (movement between the class of one's parents and one's own) from intragenerational mobility (movement within one's own working life), and, more importantly, absolute from relative mobility. Absolute mobility measures the total amount of movement (much of which reflects changes in the occupational structure - more room at the top as manual jobs decline), while relative mobility measures the comparative chances of people from different origins reaching a given destination - a truer test of fairness.

The evidence, presented as broad patterns rather than precise figures, shows substantial absolute mobility (many people occupy different positions from their parents, largely because the occupational structure has changed) but much more limited relative mobility (the comparative advantage of those from higher origins in reaching higher destinations has been remarkably persistent). In other words, there is more room at the top, but the children of the advantaged remain disproportionately likely to occupy it. This distinction is crucial: it explains how a society can appear mobile and meritocratic while continuing to reproduce advantage.

The significance of mobility connects to the theories and to the concept of life chances. Functionalists and the New Right cite mobility as evidence that society is open and meritocratic, rewarding talent and effort; Marxists and Weberians emphasise the limits of relative mobility and the persistence of class advantage, arguing that the meritocratic story is largely a legitimating myth. Barriers to mobility - unequal education (cultural capital), the reproduction of advantage through networks and wealth, and discrimination - explain why origins continue to shape destinations. Life chances, the probability of accessing valued resources by social position, are the concrete expression of these persistent inequalities.

Evaluating social mobility means using the absolute/relative distinction to assess how open society really is, and connecting it to the wider debate about stratification. The persistence of limited relative mobility is strong evidence against the functionalist and New Right claim of a genuinely open, meritocratic society, and supports the Marxist and Weberian emphasis on the reproduction of advantage - though the reality of substantial absolute mobility must be acknowledged. The strongest answers use mobility evidence to reach a judgement about the openness of the class structure, connect it to life chances and to the earlier theories, and treat all mobility data as broad, well-established patterns rather than precise official statistics.

Worked example

Analysing limited relative mobility

Applying material from the Item, analyse two reasons why relative social mobility remains limited.

Select reason one from the Item
Hook to a reference to education and develop unequal schooling: cultural capital and the middle-class advantage in education (Bourdieu) reproduce origins as destinations.
Develop and link
Explain the mechanism (advantaged children gain educational credentials -> better destinations) and connect to the reproduction of class.
Select reason two from the Item
Hook to a reference to family resources and develop the transmission of advantage: wealth, networks and social capital help the advantaged secure top positions.
Develop and link
Note that these mechanisms explain why high absolute mobility (from occupational change) coexists with low relative mobility.

Result: A full-mark 10-marker develops exactly two reasons for limited relative mobility - unequal education and the transmission of advantage - each hooked to the Item with a clear mechanism, distinguishing relative from absolute mobility.

Typical mistakes

Confusing absolute mobility (total movement, driven by occupational change) with relative mobility (comparative chances) - the distinction is decisive.
Citing precise 'statistics' from memory - present mobility as broad, established patterns.
