Joseph A. Schumpeter, “Die sozialen Klassen im ethnisch homogenen Milieu” (1927)

This file is a single-author theoretical sociological article. Its scope is general class theory under an abstraction: the “ethnically homogeneous milieu” brackets race in order to isolate why classes exist at all. Schumpeter’s thesis is that classes are real social formations whose rank and membership are generated by differential family aptitudes for socially necessary functions, especially leadership; once achieved, rank hardens into a durable class milieu.

Part I is conceptual. Schumpeter rejects the confusion between real social classes and classificatory groups invented by economists, such as landowners, laborers, or factor-income categories.

Diese Klassen sind Klassen nur in dem Sinn von Resultaten der Klassifikation der Wirtschaftssubjekte durch den Forscher.

English translation: These classes are classes only in the sense of being the results of the researcher's classification of economic subjects.

Real classes are recognized not by income tables but by manners, association, mutual understanding, and especially socially accepted marriage (connubium). He distinguishes four problems—class essence/function, cohesion, formation, and historically specific class structures—and focuses on formation.

Parts II and III recast class as movement through families. Beginning with the fiction of closed class barriers, Schumpeter asks why some families rise or fall within a class. Chance is too incidental, and Marxian accumulation too automatic: capital does not invest itself. In the Staufen nobility, ascent depends on marriage policy, management of feudal position, service, war, and domination. In capitalism, thrift and efficient routine matter, but decisive ascent comes from entrepreneurial departure from routine.

Weder das Sparen noch die prompte Geschäftsführung als solche, sondern das Bewähren an dieser Aufgabe ist das Entscheidende.

English translation: Neither saving nor prompt business management as such, but proving oneself in this task, is what is decisive.

In large corporations and trusts the type changes again: stamina, committee work, appointment, negotiation, and political skill can separate personal advancement from the success of the firm. Yet the principle remains “Verhalten” and “Eignung,” conduct and aptitude, not mere objective location.

Class barriers are therefore real but never absolute. The decisive unit is the lineage, not the physical person:

Nur das physische Individuum ist klassengeboren, die Familie nicht.

English translation: Only the physical individual is born into a class, not the family.

Schumpeter’s image makes stability and turnover compatible:

Jede Klasse gleicht während der Dauer ihres Kollektivlebens oder der Zeit, während welcher ihre Identität angenommen werden kann, einem Hotel oder einem Omnibus, die zwar immer besetzt sind, aber von immer andern Leuten.

English translation: During the duration of its collective life, or the time during which its identity can be assumed, every class resembles a hotel or an omnibus that is always occupied, but by ever different people.

Crossing class boundaries is not an anomaly; it is the very process by which a class obtains its family content. A class may look continuous because its style, prestige, and institutions persist while its constituent families are replaced.

Part IV extends the argument from families to whole classes. A class rises or falls with the social importance of the function attached to it and with its success in performing that function.

Immer und ohne alle Ausnahmen ist jede Klasse mit einer solchen besonderen Funktion verbunden.

English translation: Always and without any exceptions, every class is connected with such a particular function.

The long case is the Germanic and feudal nobility. It rises because warrior leadership is central in a world where armed conflict is a normal form of life; military service becomes rule, land, office, and prestige. It declines when war ceases to be the nobility’s living function. Patrimonialization turns offices, land, and personality into inherited or private assets, while the modern state machine absorbs domination. Privilege remains, but as residue after the original function has weakened. Social functions are ranked by their relation to leadership and by the replaceability of those who perform them.

Part V condenses the theory. Classes are neither immutable castes nor economic income groups; they are hardened results of family success around socially necessary tasks.

Die Ursache, auf der letzten Endes das Klassenphänomen beruht, sind die individuellen Eignungsdifferenzen.

English translation: The cause on which the phenomenon of class ultimately rests is individual differences in aptitude.

These aptitudes are not moral merit and not simply biology. They may be natural, acquired, inherited, or trained, and they work through property, prestige, tradition, education, and recruitment. Schumpeter’s leadership concept is deliberately dry rather than heroic:

Soziale Führerschaft ist Entscheiden, Befehlen, Durchsetzen, Vorangehen.

English translation: Social leadership is deciding, commanding, carrying through, going in front.

The essay’s relevance lies in joining class theory to mobility, elite circulation, and entrepreneurship. Its key move is to explain class durability through “Festwerden,” the hardening and survival of achieved positions, while showing continuous family turnover beneath apparent class stability.
