Capitalism is an economic system based on private ownership, competition, and profit motive. Of course, Adam Smith and Milton Friedman defend free-market capitalism as the best driver of human happiness and progress, while Carroll, Elkington and Porter & Kramer suggest that socially responsible capitalism – such as would not be dehumanising – is possible. However, critics such as Naomi Klein emphasise the structural harms inherent in capitalism, rejecting the idea that it can be regulated and tamed and made compatible with human flourishing. Catholic social teaching from Vatican II onwards has also expressed concern about the dehumanising potential of unregulated markets. Gaudium et Spes (1965) highlights the dangers of reducing humans to economic agents, while Populorum Progressio (1967) criticises global economic inequality and calls for solidarity with the poor. More recent encyclicals, such as Centesimus Annus (1991) and Laudato Si’ (2015), reinforce the Church’s critique of profit-driven systems that neglect human dignity and environmental stewardship. In addition, Liberation Theology drew on Marxist analysis to argue that economic structures, such as capitalism, can perpetuate structural sin and systemic injustice, making exploitation an intrinsic feature of the system. This essay argues that while capitalism has features that can be exploitative and dehumanising, these harms can be mitigated through regulation and Corporate Social Responsibility.

One reason capitalism can be seen as exploitative and dehumanising is its prioritisation of profit over people, which can entrench structural injustice. Liberation Theologians such as Gustavo Gutiérrez and Leonardo Boff, drawing selectively on Marx, argue that capitalism perpetuates structural sin by marginalising the poor and commodifying human labour. Workers are often alienated from the products of their labour, while wealth and power concentrate among elites. Naomi Klein, in This Changes Everything (2014), highlights how profit-driven imperatives exacerbate social inequality and environmental degradation, disproportionately harming vulnerable communities. Catholic social teaching echoes these concerns: Gaudium et Spes warns against reducing humans to “economic instruments,” and Populorum Progressio emphasises the moral duty to restructure global economies to serve human development rather than mere profit. Marx’s concept of alienation aligns with these critiques: when labour becomes a commodity, human creativity, dignity, and social relationships are undermined. In this sense, capitalism’s focus on profit can be both exploitative, by extracting value from workers and resources, and dehumanising, by instrumentalising people.

A second reason capitalism may be dehumanising is its tendency to externalise costs, particularly social and environmental ones. Naomi Klein and other critics argue that unregulated markets often prioritise short-term gain over long-term sustainability, disproportionately affecting the poor and future generations. Catholic social teaching reinforces this critique: Centesimus Annus (1991) stresses that while private property is legitimate, it must serve the common good, warning that excessive accumulation of wealth can lead to social injustice and moral harm. Laudato Si’ (2015) extends this to ecological concerns, highlighting how profit-driven exploitation of natural resources degrades the environment and threatens human dignity. Business Ethics scholars provide frameworks to mitigate these harms. Archie Carroll’s CSR pyramid encourages companies to address economic, legal, ethical, and philanthropic responsibilities; John Elkington’s triple bottom line integrates environmental and social concerns with profit; Porter & Kramer’s shared value approach demonstrates that businesses can generate economic value while contributing positively to society. These models show that capitalism need not be inherently dehumanising, but its incentives make exploitation and disregard for human and environmental welfare more likely when profit is pursued in isolation.

Nevertheless, proponents of capitalism argue that it is not inherently exploitative or dehumanising, and can promote prosperity and human development. Adam Smith, in The Wealth of Nations, maintains that individuals pursuing their self-interest can contribute to overall societal wealth through the “invisible hand” of the market. Milton Friedman similarly argues that profit maximisation, within legal and ethical boundaries, provides incentives for innovation, efficiency, and job creation. From this perspective, capitalism can lift people out of poverty and expand opportunities for social mobility. Modern socially responsible approaches, such as CSR and shared value, align economic activity with ethical principles, illustrating that markets can operate without dehumanising participants. Vatican teaching recognises the legitimacy of markets when they are ethically regulated: Centesimus Annus upholds private property and entrepreneurship but insists that economic activity must prioritise human dignity and social justice. In this view, capitalism’s dehumanising effects are contingent, not inevitable. Critics, however, question whether capitalism’s structural logic can ever be fully compatible with human flourishing. Liberation Theology argues that even regulated markets may perpetuate structural sin, because power and resources remain concentrated, leaving the poor dependent and marginalised. Naomi Klein highlights systemic consequences such as environmental destruction and inequality, suggesting that ethical regulation may only partially mitigate harm. Catholic social teaching also stresses the moral limits of markets: Populorum Progressio and Laudato Si’ argue that economies must serve human and ecological well-being, not merely wealth accumulation. Marxist critique further emphasises that alienation and exploitation are intrinsic to capitalist production. While free-market advocates and Business Ethics frameworks propose reforms, critics suggest that systemic pressures for profit and growth make exploitation difficult to eradicate entirely, leaving unresolved tensions between efficiency, innovation, and human dignity.

In conclusion, capitalism has features that can be exploitative and dehumanising, particularly when profit is prioritised over human and ecological welfare. Liberation Theology and Catholic social teaching, from Gaudium et Spes through Laudato Si’, emphasise that unregulated markets can perpetuate structural sin, alienate workers, and degrade human dignity. Critics such as Naomi Klein highlight environmental and social consequences of profit-driven economies. However, ethical frameworks from Business Ethics scholars, socially responsible practices, and Vatican teaching show that capitalism is not inherently dehumanising. When guided by moral principles, regulatory frameworks, and a commitment to human flourishing, economic activity can generate prosperity while respecting dignity and sustainability. A nuanced understanding recognises both the potential for exploitation and the opportunities for reform, underscoring the moral responsibility to integrate ethical, social, and environmental considerations into capitalist systems.
