Key Classes in Capitalism: Bourgeoisie and Proletariat

Walk into any factory, IT park, or e-commerce warehouse and you will see two very different kinds of people. Some own the building, the machines, and the brand. Others arrive each morning, do the work, and take home a wage. Karl Marx built his entire analysis of capitalism around this single divide. For Marx, capitalist society is split into two principal classes whose interests pull in opposite directions, and understanding that split is the key to understanding how modern economies actually work.

How Marx defined class 🔗

Most people think of class in terms of income or lifestyle. Marx thought differently. For him, class is defined by ownership of property, specifically the means of production, rather than by how much money someone earns or what status they hold. Ownership of property vests a person with the power to exclude others and use it for personal gain, and it is this relationship to productive property that places a person in one class or another.

The means of production are the resources needed to produce goods and services apart from labour itself. Think of factory buildings, machinery, land, raw materials, and tools. A person who owns these resources is in a fundamentally different position from a person who owns nothing but their own capacity to work. That difference is the foundation of Marx’s whole theory.

The bourgeoisie: owners of the means of production 🔗

The first principal class is the bourgeoisie, often called the capitalist or ruling class. In the Communist Manifesto, Marx and Engels defined the bourgeoisie as the class of modern capitalists, owners of the means of social production and employers of wage labour. Factory owners, large industrialists, and major investors all fall into this category.

What sets the bourgeoisie apart is the source of their income. They do not earn their wealth primarily through their own physical labour. Instead, they earn it through profit generated by the business they own. They purchase the labour of others, control the production process, and keep the wealth that results. This control over economic resources also gives the bourgeoisie enormous political and cultural influence, which is why Marx argued that in a mature capitalist society, the state and its governing ideas tend to reflect the interests of the owning class.

Not every business owner is bourgeoisie 🔗

Marx recognised that reality is more complicated than two neat boxes. He described an intermediate group called the petty bourgeoisie, made up of small shopkeepers, self-employed artisans, and independent professionals. This group owns some means of production but also works directly in the production process, occupying a middle position between the two main classes. Marx predicted that as competition intensified, many in this group would be pushed down into the working class.

He also identified the lumpenproletariat, those with no stable connection to the productive economy, such as the long-term unemployed and the destitute. Marx was sceptical about their potential for organised political action. These categories matter because they show that Marx’s “two great classes” describe the basic structure of capitalism, not every individual within it.

The proletariat: those who sell their labour 🔗

The second principal class is the proletariat, or working class. The defining feature of the proletariat is that they own no productive property. As the Manifesto puts it, the proletariat developed into a class of labourers who live only so long as they find work, and who find work only so long as their labour increases capital. With no factories, land, or capital of their own, the only thing they can sell to survive is their labour power.

Labour power is the worker’s capacity to work, which the capitalist buys for a wage. Marxist philosophy regards the proletariat under capitalism as an exploited class, deprived of their own means of production and forced to operate machinery owned by the bourgeoisie, receiving wages worth less than the value their labour produces. This is why Marx sometimes called workers “wage slaves.” A capitalist can choose whether or not to employ workers, but a worker who does not sell their labour faces destitution. That asymmetry of power, Marx argued, makes the relationship far from a free and equal exchange.

Surplus value: where exploitation happens 🔗

The relationship between these two classes becomes clearer through Marx’s concept of surplus value. This is the mechanism that, in Marx’s view, makes capitalism inherently exploitative. To follow it, you need to separate two ideas that sound similar but are not the same: the value of a worker’s labour power, and the value that labour actually creates.

According to Marx, the capitalist pays workers less than the value their labour adds to the goods, usually only enough to keep the worker at a subsistence level. A worker might produce enough value in five hours to cover their own wages, but the capitalist employs them for ten or twelve hours. The value created in those extra hours does not go to the worker. It is appropriated by the capitalist as profit. This unpaid portion is what Marx called surplus value, and the value it produces is “surplus labour.”

Marx adhered to the labour theory of value, the idea that human labour is the ultimate source of economic value. From this, he argued that to make a profit, the capitalist appropriates surplus value, thereby exploiting the labourer. Crucially, this happens within an exchange that looks perfectly fair on the surface. The capitalist pays the full market price for labour power, just as they pay for raw materials. The catch is that labour power is a unique commodity. As Marx described it, it is a source not only of value, but of more value than it has itself. That extra value is the engine of profit.

The drive to extract more 🔗

Because surplus value is the source of profit, the capitalist is under constant pressure to increase it. Marx described several ways this happens, broadly grouped into two methods. Absolute surplus value comes from extending the length of the working day, while relative surplus value comes from raising productivity and intensifying labour, often through new technology and tighter organisation of work. The “rate of exploitation,” in Marxist economics, is simply the ratio of this unpaid surplus labour to the wages actually paid.

This drive is not, in Marx’s analysis, a matter of individual greed. It is structural. A capitalist who refuses to maximise surplus value will be outcompeted by rivals who do not. The logic of the system itself compels the constant squeezing of more value out of labour.

Why the two classes are in conflict 🔗

This economic relationship explains why Marx saw class antagonism as built into capitalism rather than as an accident that could be fixed by goodwill. The interests of the two classes are directly opposed. The bourgeoisie’s profit grows when wages are kept low and the working day is long. The proletariat’s wellbeing improves with the exact opposite. One class gains precisely what the other loses, which is why Marx and Engels famously described society as splitting into two great hostile camps, two great classes directly facing each other.

The Communist Manifesto opens with the line that the history of all hitherto existing society is the history of class struggles. Earlier societies had their own oppressing and oppressed classes, such as masters and slaves, or lords and serfs. Capitalism, in Marx’s view, did not abolish class conflict. It simplified it, stripping away the older complications and leaving two clearly defined antagonists.

From class “in itself” to class “for itself” 🔗

Marx argued that exploitation does not automatically produce rebellion. Workers first exist as a class “in itself,” sharing the same economic position without recognising it. The transformation into a class “for itself” happens when workers develop class consciousness, an awareness of their shared interests and their common opposition to the bourgeoisie. Modern industry, by bringing large numbers of workers together in factories and cities, was supposed to make this awareness easier to develop.

Marx believed this dynamic would eventually push the system toward crisis. In one of his most quoted predictions, he wrote that the bourgeoisie produces, above all, its own grave-diggers. By creating an ever larger and more organised working class, capitalism was, in Marx’s view, generating the very force that would eventually overturn it and lead toward a classless society.

Reading Marx in today’s economy 🔗

It is worth asking how well this two-class model fits the present. The structure of work has changed enormously since the nineteenth century. A large services sector, salaried professionals, and a growing gig economy of delivery riders, drivers, and freelancers complicate the picture. Some scholars note that the terms “bourgeoisie” and “proletariat” struggle to capture everyone, from billionaire CEOs to app-based workers who own their own scooter but still depend entirely on a platform for income.

Even so, the core relationship Marx identified remains visible. The basic question of who owns the productive assets and who must sell their labour to survive still shapes debates about wages, labour rights, contract work, and economic inequality. Whether you accept Marx’s conclusions or not, his framework remains one of the most influential tools ever developed for analysing how economic power is distributed in society.

What do you think? Does Marx’s division of society into owners and workers still capture the reality of today’s gig and platform economy, where someone might own their tools yet depend completely on a company for work? And if labour creates value, how should the rewards of that value be shared between those who own capital and those who supply the work?
