When the Second World War ended, Marxist thinkers faced an uncomfortable puzzle. Capitalism had not collapsed under the weight of its own contradictions, as classical theory predicted. Instead, it had stabilised through welfare programmes, rising consumption, and parliamentary democracy. Workers in advanced economies seemed reasonably content, not on the verge of revolt. This forced a generation of theorists to ask a sharper question than Marx himself had answered fully: what exactly is the state, and how does it keep a deeply unequal system running so smoothly? The answers that emerged-from Ralph Miliband, Louis Althusser, Nicos Poulantzas, and Herbert Marcuse-reshaped how we understand power, the state, and the role of civil society in holding capitalism together.

Why the post-war debate mattered
Classical Marxism offered a compact image of the state. In The Communist Manifesto, the modern state was described as little more than a committee managing the shared affairs of the bourgeoisie. For decades, many Marxists treated this as self-evident and rarely tested it in detail. The post-war world made that complacency impossible.
Capitalist states were now doing things that looked, on the surface, anti-capitalist: building public housing, expanding education, granting trade union rights, and running large public sectors. If the state simply served the rich, why would it concede so much to workers? This tension produced a rich debate inside Marxism about whether the state is a passive tool of capitalists or something with a logic of its own. The discussion mattered for civil society too, because it placed institutions like schools, churches, the media, and the family at the centre of how power is reproduced.
Ralph Miliband and the instrumentalist view of the state
The British sociologist Ralph Miliband gave the debate its starting point with his 1969 book The State in Capitalist Society. His argument is often labelled the instrumentalist theory, because it treats the state as an instrument wielded by the dominant economic class.
The state as the ruling class’s instrument
Miliband set out to do what earlier Marxists had skipped: actually prove that the state serves capital, rather than just assert it. He examined who staffs the senior levels of the state-the civil service, the judiciary, the military command, the senior bureaucracy-and found that they overwhelmingly came from privileged backgrounds, elite schools, and propertied families. In the exchange that followed, this empirical, who-runs-it approach became his trademark. Because the people who control the state share the worldview, education, and social ties of the owning class, the state predictably acts to protect existing economic and political inequalities.
Reform and repression
Miliband did not think the state always relies on force. He argued that when a capitalist state faces rising pressure and demands from below, it tends to respond in two ways. First, it offers reform-but reform that stays largely symbolic, because it cannot break the fundamental limits of the system it defends. Second, when reform fails to pacify discontent, the state turns to repression, curtailing the very democratic rights it claims to uphold. From this he drew a striking conclusion: the smooth transition from capitalism to socialism may be a myth, but the slide from bourgeois democracy into a more authoritarian, conservative order is entirely possible.
The structuralist challenge
Miliband’s account was powerful, but a rival camp argued it was looking in the wrong place. For the structuralists, the class background of officials was almost beside the point. What mattered was the structure of capitalism itself, which constrains the state regardless of who happens to be in charge.
Althusser’s repressive and ideological state apparatuses
The French philosopher Louis Althusser supplied the theoretical foundation for this view. In his influential 1970 essay on ideology and ideological state apparatuses, Althusser argued that the ultimate condition for any economic system is the constant reproduction of the conditions of production. A factory does not just make goods; society must also reproduce a workforce that turns up, obeys rules, and accepts its place. How does this happen?
Althusser split the state into two interlocking sets of institutions. The Repressive State Apparatus (RSA)-the government, administration, army, police, courts, and prisons-functions primarily through force or the threat of it. There is only one such apparatus, firmly in the public domain. Alongside it sits a plurality of Ideological State Apparatuses (ISAs): religion, education, the family, the legal system, the political system, communications, and culture. These function primarily through ideology rather than violence, and many of them sit in what we usually call the private sphere of civil society.
For Althusser, education was the dominant ISA in modern societies, quietly teaching not just skills but obedience, ambition, and acceptance of one’s role. The genius of the system, in his view, is that it does not look like coercion at all. People internalise the ruling ideology and come to see an exploitative arrangement as natural, even fair. Both apparatuses ultimately work to secure the reproduction of capitalist relations of production.
Poulantzas and the relative autonomy of the state
Nicos Poulantzas, a Greek-French theorist heavily influenced by Althusser, pushed this structural logic into a direct theory of the state. His central concept was the relative autonomy of the state. The state, he argued, must stand somewhat apart from the direct control of any single capitalist or faction. Capitalists are often divided and short-sighted, each pursuing immediate profit. If the state simply obeyed them, it could not manage their conflicts or make the longer-term concessions-like welfare or labour rights-needed to keep the whole system stable.
By enjoying a degree of independence, the state can act in the general interest of capital even against the wishes of particular capitalists. Its function is structural, not personal: it organises the dominant classes and disorganises the dominated ones, ensuring the long-term survival of the system. On this view, swapping out the officials would change very little, because the role is fixed by the structure, not by the individuals filling it.
The Miliband-Poulantzas debate
These two positions collided in a famous exchange published in the New Left Review between 1969 and 1976. Poulantzas opened with a review of Miliband’s book. He praised it for challenging mainstream pluralist theory but accused Miliband of a basic error: by focusing on the personal motives and connections of the “state elite,” Miliband had reduced classes and the state to relationships between individuals. According to the record of the debate, Poulantzas insisted that classes and the state are objective structures, and that the individuals running them are merely the bearers of structural roles.
Miliband fired back. He charged Poulantzas with “structuralist abstractionism”-a theory so detached from real history and evidence that class struggle dissolved into an empty formal exercise. If everything is determined by structure, he asked, what is left for actual political agency and analysis of real institutions? Each accused the other of a hidden error: Miliband saw Poulantzas as smuggling in economic determinism, while Poulantzas saw Miliband as ignoring the system in favour of personalities. Interestingly, both men ultimately rejected the neat labels of “instrumentalist” and “structuralist” pinned on them. The lasting value of the clash was not a winner but a richer set of questions about how structure and agency combine in the state.
Herbert Marcuse and rational irrationality
While these thinkers debated the state, Herbert Marcuse of the Frankfurt School zoomed out to ask why people consent to a system that exploits them. His answer, developed in One-Dimensional Man (1964), introduced the idea that advanced industrial society runs on a kind of rational irrationality.
False consciousness and one-dimensional society
Marcuse argued that modern capitalism buys consent through abundance. It offers a “comfortable, smooth, reasonable, democratic unfreedom.” People are kept satisfied with consumer goods and a sense of free choice, even as that very choice locks them deeper into a life of toil and consumption. He distinguished between true needs-nourishment, shelter, culture-and false needs imposed from above to keep the engine of consumption running.
The result is a flattening of critical thought into what Marcuse called one-dimensional thinking. People lose the ability to imagine an alternative society, because the existing one defines the limits of the thinkable. As the Stanford Encyclopedia of Philosophy notes, domination in this society no longer needs a visible authority figure; it operates quietly through administration, technology, and the rationality of efficiency itself.
Why revolution becomes harder
Here lies Marcuse’s twist on rationality. A system can be perfectly rational in its methods-efficient, productive, technologically advanced-while being irrational in its ends, sustaining waste, ecological destruction, and the constant threat of war. The sweeping rationality that drives growth, he wrote, is itself irrational. People accept this systematic irrationality because of a deep false consciousness, in which the satisfaction of manufactured needs feels like genuine fulfilment.
This poses a serious problem for revolutionary politics. If the working class has been absorbed into the system and identifies with it, the classical agent of change has gone quiet. Marcuse looked instead to outsiders-students, marginalised groups, and radical intellectuals-to keep critical thought alive, a stance that made him a key inspiration for the New Left and the protests of 1968.
What this means for civil society
Taken together, these thinkers shifted Marxist attention away from a narrow focus on government and toward the wider terrain of civil society. The lesson running through Althusser, Poulantzas, and Marcuse is that power is reproduced not mainly in parliaments and police stations, but in classrooms, newsrooms, advertising, religious life, and the household. These institutions shape how people think long before any law is enforced.
That insight remains directly relevant to understanding any modern democracy. When citizens broadly accept the existing order as natural, the state rarely needs to reach for repression. The everyday institutions of civil society do the quieter, more durable work of securing consent-which is precisely why control over education, media, and culture is always a site of political struggle.
What do you think? Is the state in your own society better understood as an instrument grabbed by the powerful, or as a structure that constrains whoever governs? And if Marcuse is right that comfort and consumption can dull the appetite for change, what would it take to think genuinely beyond the system we already live in?
