Proletariat: Definition & Meaning

The proletariat is the working class or lower class in society who live solely from selling their labor power and do not own the means of production. They are viewed in Marxism as the revolutionary class with the potential to overturn capitalism.

1. Defining the Proletariat

In Marxist theory, the proletariat is the social class of wage labourers who do not own the means of production. They own no factories, tools, land, or raw materials.

In The Communist Manifesto, Marx and Engels assert that proletarians live only so long as they find work, and find work only so long as their labour increases capital.

Consequently, the labourer becomes a commodity, exposed to all the vicissitudes of competition and market fluctuations.

  • Economic Position: Because they own no means of production (factories, land, or tools) and must sell their labor power to survive.

  • Opposition to the Bourgeoisie: The proletariat is defined by its binary struggle against the bourgeoisie; the capitalist seeks to maximize profit by extracting “surplus value,” while the worker seeks to maximize wages.
  • The Alienated Wage Slave: Unlike a slave, who is sold once, a proletarian must sell themselves daily, hour by hour. They are “legally free” but economically chained to the necessity of finding a boss.

The proletariat is described as a specific product of the Industrial Revolution, precipitated by the invention of the steam engine and other machinery.

Poor and working classes have always existed. But the proletariat is a distinct historical phenomenon. It was created when machinery altered the mode of production, displacing former handicraftsmen and delivering industry entirely into the hands of big capitalists.

A class, in this sense, is a group of people who share a common relationship to whatever counts as the means of production in their society. Before industrialisation, that relationship centred on land: those who owned it, and those who worked it without owning it.

Industrialisation changed that. The decisive resource shifted from land to capital: factories, machinery, and the money needed to buy them.

A medieval serf, however poor, usually kept direct access to a strip of land and its produce. A 19th-century factory hand had nothing to sell but the capacity to work itself.


2. Examples of the Proletariat

1. The Classic Industrial Core (The “Old” Proletariat)

This group represents the traditional “working class” for whom the 20th-century welfare state was built .

  • Factory Workers: Spinners, weavers, and assembly-line workers who are “appendages of the machine”.

  • Detail Labourers: Workers who perform a single, repetitive task in a complex manufacturing process (e.g., dial makers or screw polishers) .

  • Miners: Workers in coal and metal extraction who endure dangerous, regimented conditions.

  • Proletarianized Salariat: Lower-level civil servants or corporate employees with tenure who lack control over their work process .

2. The Agricultural Proletariat

These are workers “expropriated” from the land, owning no tools or soil

  • Day Labourers: Agricultural workers who sell their labour power to capitalist farmers for a money wage.

  • Migratory Farm Workers: Internal or international migrants who work seasonal crops and often lack the legal rights of citizenship (denizens).

3. Modern Service and “Pink-Collar” Jobs

Contemporary sociology identifies these as service-sector roles that mirror factory conditions through high regimentation and low control.

  • Fast Food Workers (“McJobs”): Highly scripted roles with strict oversight and low pay.

  • Call Centre Operators: Workers in a “digital factory” environment where every second of their time is monitored.

  • Checkout Clerks and Cashiers: Retail staff who sell their labour power and have no ownership of the enterprise.

  • Day-Care and Restaurant Servers: Low-wage service roles primarily held by women, often characterized by “status frustration” if the worker is over-educated for the task .


3. Historical Origins: How the Class Was Created

The proletariat was a specific product of the Industrial Revolution (late 18th to 19th century).

Marx described its birth as being written in “letters of blood and fire.”

Expropriation of the Peasantry (The “Push” Factor)

Before the industrial era, many peasants had access to “common lands” for grazing and fuel.

The great feudal lords created a massive proletariat by forcibly driving the peasantry from land they held under the same feudal title as the lords themselves. The lords also usurped the common lands.

  • The Enclosure Movement: Powerful landowners used legal and physical force to fence off their lands for large-scale sheep farming (for the wool trade).

  • Expropriation: Agricultural populations were swept off the land to make room for sheep or deer forests, often leaving no place for the displaced to live.

  • Displacement: Millions of people were “hurled onto the labor market” as “free” individuals, free from feudal ties, but also “free” from any way to feed themselves without a boss.

The Rise of Machinery (The “Pull” Factor)

If the loss of land provided the people for the new working class, the invention of machinery provided the system that trapped them.

The Steam Engine, Spinning Jenny, and Mechanical Loom were not just tools; they were the catalysts for a total social revolution.

1. The Destruction of Handicrafts

In the pre-industrial “Putting-Out System” (or Cottage Industry), workers often worked from home.

While they sometimes rented equipment, many owned their hand-looms or spinning wheels.

They had a degree of control over their hours and the pace of their work.

Marx referred to these small-scale tools as “scanty property” because they were enough to provide independence but not enough to generate massive capital.

  • The Shift: During the industrial revolution, new machines were massive and expensive, affordable only by wealthy capitalists. A hand-loom could fit in a cottage; a steam-powered power loom required a factory building and a massive engine.

  • The Consequence: Hand-made goods could not compete with machine-made goods in price or speed. The artisan’s tools became worthless overnight, and their independence was destroyed. Industry was now consolidated in the hands of the few.

2. The “Sinking” of the Middle Class

The machine system acted as a vacuum, sucking the lower levels of the middle class into the proletariat.

  • The Financial Barrier: Small-scale tradespeople and master craftsmen didn’t have enough capital to build factories or buy modern machinery.

  • Loss of Value: Their specialized, lifelong skills were rendered obsolete by machines that could be operated by unskilled laborers.

  • The Result: This “lower strata” of the middle class lost their status and were forced to join the ranks of the wage-laborers to survive.

3. From the Workshop to the Factory

Marx identified a critical shift in how work was done, moving from “Manufacture” to “Modern Industry.”

  • The “Detail Labourer”: In early manufacturing, a human still controlled the tool, but the job was broken down into tiny, repetitive steps.

  • The “Appendage of the Machine”: In the modern factory, the machine takes over the tool. The worker no longer directs the work; they simply serve the machine—feeding it material or clearing jams.

  • Mental vs. Manual Labour: This completed the “intellectual separation” of work. The machine held the “knowledge” and “skill,” while the worker provided only raw, mindless physical labor.

Thompson (1963): Class as Something Made, Not Merely Given

Enclosure and machinery explain how a proletariat became economically possible. They do not, by themselves, explain how displaced workers came to think of themselves as members of a single class with shared interests. Historian E. P. Thompson tested this directly.

  • Aim: to test whether a shared working-class identity in England (1780s-1830s) followed automatically from factory employment, or had to be actively built by workers themselves.
  • Method: a close reading of primary sources from the period, including trade clubs, radical pamphleteering, and early trade unionism, treated as direct evidence of workers building a shared identity.
  • Results: a recognisably working-class identity did not spring up automatically. It took decades of organising, shared experience of state repression, and sustained cultural work before a class consciousness had crystallised (Thompson, 1963).
  • Conclusion: class is not a fixed category read off an occupational census. It is a historical relationship that “happens” in workers’ own lived experience and agency.

This remains one of the most influential correctives to a purely economic reading of the proletariat’s formation.

Its limits are those of any single-country study. It reconstructs one nation across one half-century and risks under-representing groups such as women and the very poorest, whose activity left a thinner documentary record.


4. The Experience of Labor: Alienation

Marx argued that capitalism strips the worker of their humanity, a process called alienation. This manifests in four ways:

The Four Dimensions of Alienation

Because the worker has no control over their environment, they experience a profound “estrangement”:

  1. From the Product: The object they build stands against them as an “alien power” that they cannot afford to buy.

  2. From the Process: Work is not a creative expression but a monotonous, forced activity. The worker becomes an “appendage of the machine.”

  3. From Others: Workers are forced to compete for shifts and “piece-rates,” destroying social solidarity.

  4. From the Self: Marx called this “Species-Being.” By losing the ability to direct their own creative labor, humans lose what makes them uniquely human.

Surplus Value and Subsistence

The worker does not receive the full value of what they produce. Instead, they receive subsistence wages, just enough to keep them alive and capable of returning to work the next day.

The difference between the worker’s wage and the sale price is the surplus value. The capitalist keeps it as profit, not the worker.

This is the same mechanism Marx worked out in detail in the labor theory of value. It also explains why the minimum wage matters: it sets how much of that value is returned to the worker as pay, instead of kept as profit.


5. Class Consciousness and Conflict

Marx believed the proletariat’s miserable conditions would eventually lead to a revolution.

False Class Consciousness

The ruling class maintains power through ideology.

By controlling the media, education, and religion, the bourgeoisie leads the proletariat to believe that their poverty is their own fault or that “working hard” will eventually make them millionaires.

This prevents the formation of Class Consciousness (the realization of shared oppression).

  • False Class Consciousness: A state where workers believe the system is fair or that they can become “the boss” if they just work harder. They accept their oppression as “normal.”

  • Class Consciousness: The “awakening” where the proletariat realizes they are a distinct class with shared interests. They move from being a “class in itself” (a group of people with the same job) to a “class for itself” (a political force).

  • The Outcome: Marx predicted that the proletariat would eventually overthrow the bourgeoisie, leading to a system where workers control their own labor and profits.


6. Modern Sociological Perspectives

Since Marx’s death, the definition of the proletariat has evolved to fit modern society.

Embourgeoisement vs. Proletarianization

Both ideas make a testable claim about the direction of change, not just an armchair prediction; the evidence is examined in Critical Evaluation, below.

  • Embourgeoisement (Post-WWII): In the 1950s/60s, rising standards of living led some to argue the working class was becoming “middle class” (owning homes, cars, and adopting conservative values) (Rinehart, 1971).

  • Proletarianization: Modern “white-collar” jobs (like teaching or office work) become more like factory work over time: monotonous, lower-paid, and heavily monitored, stripping away their professional status (Larson, 1980; Wright & Singelmann, 1982).

Economic Position (Social Income)

  • Fictitious Decommodification: During the 20th century, the proletariat experienced fictitious decommodification, where their remuneration shifted from just money wages to a mix of enterprise and state benefits (like pension funds).
  • Dependence on Stability: This made the proletariat dependent on staying in stable, full-time jobs for long periods to access their “rights”.


The Decline of the Industrial Proletariat: Deindustrialisation

The industrial core described above (factory workers, miners, detail labourers) has shrunk sharply since the 1970s. Economists call this deindustrialisation: corporations closing domestic factories and relocating production to lower-wage regions (Bluestone & Harrison, 1982).

The jobs that replaced it were rarely as good.

Lost manufacturing work was mostly replaced by lower-paid, less secure service-sector positions. So the shrinking industrial proletariat has not meant fewer proletarians overall, but a redistribution of the working class toward more precarious service roles.

This shift has not fallen evenly.

Research on American inner cities found that stable, unionised factory jobs disappeared disproportionately from Black urban communities. For these communities, manufacturing had been one of the few realistic routes to a secure income (Wilson, 1996).

7. The Rise of the Precariat

Sociologist Guy Standing argues that a new class has emerged: the Precariat.

This precariat consists of workers with no job security, often on “zero-hour” contracts or temporary gigs.

  • Gig Economy Workers: Uber drivers or delivery couriers who own some tools (a car or bike) but are dependent on a platform (the means of production) they do not control.

  • Crowd-Labourers: People performing micro-tasks online for global platforms, often without any legal labour rights.

  • Temporary Agency Staff: Workers who are “in and out of jobs” without long-term employment contracts.

  • Interns and “Freeters”: Young people in casual labour who are required to have higher qualifications than the work they perform.

Even if they are highly skilled, they lack the stability of the traditional 19th-century working class.

Unlike the 19th-century proletariat who were habituated to stable labor, the precariat is habituated to unstable labor and unstable living.

They perform a high ratio of work-for-labour, unpaid activities like retraining, searching for jobs, and navigating bureaucracy, which is not remunerated but essential for survival.

Feature 19th-Century Proletariat (Marx) 21st-Century Proletariat (Guy Standing)
Class Position

The overwhelming majority and “vanguard” of change.

A shrinking “core” losing its sense of social solidarity.

Primary Goal Overthrow of the capitalist system.

Protection of “labour rights” and stable employment.

Relation to Rights Lacked legal and social rights.

Defined by “industrial citizenship” and social insurance.

Remuneration

Pure money wage (commoditized labor).

Mix of wages, pensions, and enterprise benefits.

Identity

Strong occupational identity and “social memory”.

Shrivelling battalions with a weakened political voice.

The precariat is a “dangerous class” because it is internally divided, with different groups experiencing different forms of deprivation:

Faction Origin/Background Political Risk
Atavists

People falling out of old manual-labor communities.

Often lured by reactionary populism and the far-right due to a sense of a “lost past”.

Nostalgics

Migrants and minorities who feel they have “no present” or home.

Tend to be politically passive until sparked into “days of rage” by direct threats.

Progressives

Highly educated youth whose qualifications exceed the labor they perform.

Suffer from “status frustration” but represent the “vanguard” capable of transformative change.

Critical Evaluation

The idea of the proletariat has real analytical power. A single test, whether someone owns productive assets or must sell their labour to survive, organises a huge range of facts about pay, working conditions, and vulnerability to downturns. It has also drawn sustained, well-founded criticism.

The strongest of these criticisms are worth taking one at a time.

  • Growing Internal Heterogeneity: a single category now has to stretch to cover jobs that differ enormously in pay and power.
  • Mixed Evidence on Change: the two classic mid-century tests of the proletariat’s direction cut in different ways.
  • Class as Made, Not Given: a shared economic position does not automatically produce a shared political identity (see Historical Origins, above).
  • Neglect of Gender and Race: classical accounts said little about how gender and race shape experience within the working class.
  • The Failure of the Predicted Revolution: no advanced capitalist economy has undergone the revolution Marx predicted.

Growing Internal Heterogeneity

Marx’s proletariat was overwhelmingly manual and industrial.

Today the category has to stretch to cover assembly-line workers, call-centre operators, delivery couriers, and a “proletarianised salariat” of tenured but powerless clerical staff. These jobs differ enormously in pay, conditions, and market power.

All of them technically own no means of production.

A tenured lower civil servant and a zero-hours delivery courier both pass that test equally. Yet they differ enormously in security and autonomy, a gap sociologist Max Weber’s rival class scheme was built to capture.

Erik Olin Wright made a related point.

He called supervisory and lower-management roles “contradictory class locations,” positions that combine elements of both exploiter and exploited at once. A fuller side-by-side comparison of the proletariat and the bourgeoisie is treated separately.

Mixed Evidence on the Direction of Change

Two studies tested this directly. Rather than debate the proletariat’s direction in the abstract, both checked it against real data.

Goldthorpe, Lockwood, Bechhofer, and Platt (1969) studied highly paid manual workers at affluent factories in Luton, chosen because embourgeoisement should have been most visible there if it occurred anywhere. The result was clear.

The workers had reached consumption standards matching white-collar workers, but had not adopted middle-class social patterns. They still socialised chiefly with kin and workmates and voted overwhelmingly Labour. Embourgeoisement was not supported.

Wright and Singelmann (1982) tested the rival claim instead. They decomposed changes in the American occupational structure between 1960 and 1970 into an industry-shift component and a within-industry component.

The within-industry component showed a strong, consistent trend toward greater proletarianisation, once separated from the simple growth of service-sector jobs. Neither simple prediction was straightforwardly vindicated.

Neglect of Gender and Race

Classical accounts focused on the male industrial wage-earner.

They said comparatively little about how gender and race stratify experience within the working class. Research on deindustrialisation, discussed above, found that job losses fell disproportionately on Black urban communities (Wilson, 1996).

This was not just an economic story.

Marxist feminism develops the gendered side of this critique, including women’s unpaid domestic labour that reproduces the workforce at no direct cost to employers.

Wilson’s research also challenges a rival explanation. Some argued that declining cultural values or a weaker work ethic explained the rise in long-term joblessness in these communities.

Wilson found the structural disappearance of stable jobs explained it better than any cultural account, a pattern that recurs across the sociology of urban poverty.

The Failure of the Predicted Revolution

The heaviest weight against strong versions of Marxist theory is historical, not theoretical. Marx predicted that the proletariat’s growing immiseration and class consciousness would eventually produce a revolutionary overthrow of capitalism. No advanced capitalist economy has undergone one.

The competing explanations later Marxists have offered for this are treated in full in Major Criticisms of Marxism.

That does not mean the whole framework fails, only this specific historical prediction.

The core insight is narrower than the revolutionary prediction: total dependence on selling one’s labour power for a wage creates a distinctive, vulnerable position.

That basic economic logic has proved remarkably persistent over time.

Its concrete form has simply changed, from the cotton mill to the call centre to the delivery app.

Contemporary Research

The most active recent research front is not whether the industrial working class survives. It is what has happened to job security now that much low-wage work runs on unpredictable hours and platform-mediated tasks rather than stable employment.

Schneider and Harknett (2019) provide the best evidence here.

  • Aim: to test whether irregular, unpredictable work schedules, not just low wages, independently harm the health and well-being of hourly retail and food-service workers.
  • Method: a large-scale survey of hourly workers at major U.S. retail and food-service companies, purpose-built to capture the timing and predictability of low-wage schedules. It tested links to psychological distress, sleep quality, and happiness (Schneider & Harknett, 2019).
  • Results: schedule instability was linked to materially worse distress, sleep, and happiness, and these links were stronger than the links between low wages and the same outcomes.
  • Conclusion: how predictable a schedule is, not only how much it pays, is a major and previously under-studied driver of harm for today’s low-wage workers.

Built on a large, purpose-designed survey and published in one of sociology’s most selective journals, this sits well up the evidence hierarchy for this question. Its main limitation is that it is a single-country study of two sectors, so it may not generalise to other industries.

A related interview study looked at workers across several gig-economy platforms (Schor, Attwood-Charles, Cansoy, Ladegaard, & Wengronowitz, 2020).

It found wide variation in satisfaction and precarity. The deciding factor was not the platform itself, but whether a worker depended on that income for basic living costs.

Together, the two studies point the same way. Contemporary low-wage work still traps people into selling their labour to survive. But the mechanism generating hardship has shifted, from wage level alone toward control over time and schedule predictability.
