Karl Marx built his entire philosophy of history around one central idea: society is divided into classes, and the conflict between those classes is what drives historical change. In his view, capitalism sharpened this division to its most extreme form – pitting those who own the means of production against those who have nothing to sell but their labour. This concept of class struggle became the backbone of Marxist thought and continues to shape debates about inequality, power, and social justice today.

The two primary classes in capitalism
At the heart of Marx’s analysis are two fundamental classes defined not by income or social status, but by their relationship to the means of production. According to Marxian class theory, a person’s position in the class hierarchy depends on whether they own productive resources – factories, land, machinery – or must work for those who do.
The bourgeoisie (the capitalist class) owns the means of production. Factory owners, industrialists, and major investors fall into this category. They purchase the labour power of others, control the production process, and extract profit from the goods and services workers create. Their wealth comes not from their own physical labour, but from the surplus value generated by those they employ. As Marx explained, the capitalist pays workers only a fraction of the value their labour produces and keeps the rest as profit.
The proletariat (the working class) owns no productive property. Workers survive by selling their labour power to the bourgeoisie in exchange for wages. They produce the actual goods and services that generate wealth, yet they have no ownership stake in what they create. This relationship, Marx argued, is inherently exploitative – the very structure of capitalism depends on paying workers less than the full value of their output.
Beyond the two main classes
Marx also recognised intermediate groups. The petite bourgeoisie – small shopkeepers, independent artisans, freelance professionals – occupy a middle position. They own some means of production but also work directly in the production process. Marx predicted this group would gradually be absorbed into either the bourgeoisie or the proletariat as capitalism matured and competition intensified. There was also the lumpenproletariat, consisting of those outside the regular economy – the unemployed, beggars, and others with no stable connection to the production process. Marx was sceptical about their potential for organised political action, viewing them as more likely to be manipulated by reactionary forces than to join progressive movements.
Class conflict as the engine of history
Marx’s famous assertion in the Communist Manifesto – that all of recorded history is a history of class struggles – is the foundation of his theory of historical materialism. From the slave-master relationship in ancient Rome, to the feudal lord-serf dynamic of the Middle Ages, every era has been shaped by the conflict between an oppressing class and an oppressed class. Capitalism, Marx argued, simplified this conflict into its starkest form: bourgeoisie versus proletariat.
This conflict is not accidental. It is structural, built into the very logic of capitalist production. The bourgeoisie seeks to maximise profit, which means keeping wages low, extending working hours, and extracting the most labour possible from each worker. The proletariat, on the other hand, seeks higher wages, better working conditions, and greater control over their labour. These interests are fundamentally opposed, and this opposition generates ongoing social tension.
Marx saw this conflict evolving through stages. Initially, struggles are isolated to individual workplaces – a dispute in one factory, a strike in one industry. But as capitalism develops and conditions across workplaces become more uniform, these individual struggles become generalised into broader coalitions and eventually into society-wide class conflict. Workers begin to see their shared situation clearly and organise collectively.
Power of the bourgeoisie
The dominance of the capitalist class extends far beyond the factory floor. Marx argued that economic power translates directly into political and ideological power. Those who control the means of production also shape the institutions, laws, and ideas of society.
Control of politics and the state
In Marx’s framework, the state is not a neutral body serving all citizens equally. Rather, it functions as an instrument of the ruling class. The Communist Manifesto makes this point bluntly: the government in a capitalist society essentially manages the common affairs of the bourgeoisie. Legal systems protect private property. Taxation policy and trade regulations serve capitalist interests. The police and military enforce the existing order. Political power, in other words, is an extension of economic power.
Ideological control through the superstructure
Marx introduced the concept of base and superstructure to explain how economic relations shape the rest of society. The economic base – who owns what, and who works for whom – determines the superstructure, which includes legal, political, and cultural institutions. Education systems, media outlets, religious institutions, and cultural norms all tend to reflect and reinforce the interests of the ruling class.
This is where the concept of ideology becomes crucial. The dominant ideas in any society, according to Marx, are the ideas of the ruling class. These ideas work by making the existing social order appear natural, inevitable, and even desirable. When workers accept the belief that hard work alone determines success – ignoring structural advantages and systemic barriers – they are experiencing what Marx called false consciousness. They adopt a worldview that actually works against their own interests, preventing them from questioning the system that exploits them.
The Italian Marxist thinker Antonio Gramsci later expanded on this through his concept of hegemony – the idea that the ruling class maintains control not through force alone, but by winning the consent of the working class through ideological domination. Schools teach obedience and competition. Media celebrates individual wealth while ignoring systemic inequality. Religion encourages acceptance of suffering in this life. Together, these institutions ensure that workers consent to their own subordination without overt coercion.
Strength of the proletariat
Despite the overwhelming power of the bourgeoisie, Marx believed the working class held a decisive advantage: they are the ones who actually produce everything. Without the labour of workers, factories go silent, goods remain unproduced, and the entire economic system grinds to a halt. This gives the proletariat enormous potential leverage – when they organise and act collectively.
Shared conditions and solidarity
One of the key factors in building working-class power is what Marx described as the shared experience of exploitation. Workers in the same factory, industry, or city face similar wages, similar working hours, and similar conditions of labour. This common experience produces a natural basis for solidarity. As the Communist Manifesto noted, modern industry and transportation made it possible for workers to connect and organise far more rapidly than the medieval burghers ever could.
Marx also recognised that capitalism itself creates the conditions for worker organisation. By concentrating large numbers of workers in factories and cities, capitalist production brings people together in ways that make collective action possible. The very process of exploitation brings workers into contact with one another, creating the conditions for mutual awareness and unified action.
Nothing to lose
Another source of proletarian strength is precisely their lack of property. Because workers have no significant stake in the existing system – no factories, no land, no capital – they have less reason to defend it. The bourgeoisie, by contrast, is deeply invested in preserving the status quo because their wealth and power depend on it. This asymmetry gives the proletariat a kind of freedom: they can envision and fight for a fundamentally different social order without risking the loss of accumulated advantages.
From class in itself to class for itself
Marx drew an important distinction between what he called a “class in itself” and a “class for itself.” A class in itself is simply a group of people who share common economic conditions – they occupy the same structural position in the production process, whether they realise it or not. A class for itself, however, is one that has developed awareness of its shared interests and organises to pursue them actively.
This transformation – from a passive collection of workers to a conscious, organised political force – is what Marx called the development of class consciousness. It is the process by which workers come to understand that their individual problems (low wages, poor conditions, job insecurity) are not personal failures but structural features of capitalism. They begin to see the system for what it is and recognise their collective power to change it.
Class consciousness does not develop automatically or overnight. It grows through shared experience, through strikes and labour disputes, through the failure of individual solutions, and through political education. Marx believed that the deepening contradictions of capitalism – growing inequality, recurring economic crises, increasing precarity – would accelerate this process over time.
Revolutionary potential of the proletariat
For Marx, the ultimate outcome of class struggle under capitalism was proletarian revolution. He believed that as capitalism matured, its internal contradictions would become impossible to contain. The gap between the wealthy few and the labouring many would widen. Economic crises would become more severe and more frequent. The middle classes would be squeezed out, pushed downward into the proletariat. Society would increasingly polarise into two opposed camps.
At some point, Marx predicted, the working class – now fully conscious of its exploitation and united in purpose – would rise up, seize control of the means of production, and overthrow the capitalist system. This revolution would not simply replace one ruling class with another. Its goal was the abolition of class itself. By establishing collective ownership of productive resources, the material basis for class division would be eliminated. Without classes, there would be no need for a state apparatus to enforce class rule, and the state would gradually wither away.
Marx envisioned the resulting society as one where production would be organised to meet human needs rather than generate private profit – a classless, communist society in which, as the Manifesto puts it, the free development of each person becomes the condition for the free development of all.
Criticisms and continuing relevance
Marx’s predictions about revolution have not unfolded as he expected in most capitalist democracies. The working class has not become uniformly impoverished. A large middle class emerged, social mobility increased, and labour rights were institutionalised through unions, collective bargaining, and welfare states. Ownership and management of corporations have become separated in ways Marx did not fully anticipate.
Yet his core insight – that class position shapes life chances, that economic power translates into political influence, and that exploitation generates resistance – remains remarkably relevant. Debates about wealth inequality, gig economy labour conditions, corporate lobbying, and media ownership all echo Marxist analysis. The framework may need updating, but the questions Marx raised about who owns, who works, and who benefits remain central to understanding modern society.
What do you think? Does Marx’s division of society into bourgeoisie and proletariat still capture the reality of class in the 21st century, or has modern capitalism created class structures too complex for a two-class model? And is class consciousness – the awareness of shared exploitation – still possible in an era of individualised work and fragmented labour markets?
