Ludwig von Mises’s “The Clash of Group Interests” is a single 1945 conference/symposium essay. Across five numbered sections, it argues that modern war, revolution, protectionism, and pressure-group politics rest on a shared intellectual error: the belief that real groups can prosper only by injuring other groups.
Mises opens by rejecting the mild language of group tensions. Nationalists, racists, and Marxists differ over whether the decisive group is nation, race, or class, but all treat conflict as natural and reason as group-bound.
The natural state of intergroup relations, according to this view, is conflict.
His deeper target is polylogism: the claim that classes or races possess different logical structures. If accepted, this destroys the possibility of common argument; disagreement can be dismissed as bourgeois, non-Aryan, or treasonous. Violence then becomes not a betrayal of reigning doctrines but their practical consequence.
Our wars and civil wars are not contrary to the social doctrines generally accepted today. They are precisely the logical outcome of these doctrines.
The second section asks what makes a group a group. In caste society, law fuses individual fate to inherited privilege or disability. Liberal capitalism, by contrast, dissolves caste into juridical equality and market rivalry.
Capitalism has substituted equality under the law for the caste system of older days.
For Mises, people in the same trade are not naturally solidary; they are competitors until law creates a common privilege or burden. The shoe manufacturers become a pressure group only when tariffs or discriminatory rules make collective political action profitable.
Under free trade the manufacturers of shoes are simply competitors.
This distinction supports the essay’s central thesis: modern antagonisms are real, but they are not inherent in the free market. They are manufactured by intervention, protection, immigration exclusion, union privilege, and producer policy.
Our age is full of serious conflicts of economic group interests. But these conflicts are not inherent in the operation of an unhampered capitalist economy. They are the necessary outcome of government policies interfering with the operation of the market.
Against Marx, Mises denies that capitalists form a closed exploitative estate. Ownership is unstable, contested, and dependent on continued service to consumers. He also rejects proletarian internationalism as a myth belied by workers’ support for immigration barriers and trade restrictions. The return of privilege is, in his terms, a return toward caste.
The third section gives the argument its historical frame. Mercantilism is the old zero-sum doctrine: one nation gains only as another loses, so trade rivalry and military rivalry belong together.
Mercantilism was a philosophy of war.
Classical economics and liberalism matter because they replace this war philosophy with a theory of long-run harmony under free exchange. Mises’s utilitarian ethics is not altruistic sentimentalism; it says nations and groups should renounce conquest and privilege because these injure their own rightly understood interests.
Utilitarian ethics stands and falls with economics.
The fourth section attacks the anti-liberal climate of the age. Mises treats the left/right distinction as superficial when both camps reject rationalism, economics, utilitarianism, democracy, and market cooperation in favor of conflict doctrines. Economic ignorance lets slogans about labor, nation, and planning displace analysis of wages, capital accumulation, trade, and intervention.
The conclusion is stark. Modern society, in Mises’s view, is sliding from liberal equality toward a new caste order of pressure groups and protected producers. Constitutions and inherited habits may delay disintegration, but peace requires a social philosophy of the Great Society: a doctrine showing that individual welfare and social cooperation are mutually reinforcing.
It is a fact that the living philosophy of our age is a philosophy of irreconcilable conflict and dissociation.
The essay remains relevant as a critique of tribal epistemology and political economy. Its core conceptual move is to relocate group conflict from nature, race, or class to law-created privilege. Remove privilege, and many groups lose their warlike cohesion; multiply privilege, and society manufactures the conflicts it then calls inevitable.
