How Capitalism Generates Surplus Value Through Subsumption

In fully developed capitalism the dominant lever for increasing surplus value is relative surplus value. Absolute surplus value—gained by extending the workday or intensifying labor—becomes subsidiary once the length of the day and the intensity of work are fixed. The only remaining option to raise surplus value is to increase productivity.

The Value Trap

When productivity rises without a corresponding increase in socially necessary labor time, the value of each product falls. This creates a “value trap”: higher output does not automatically generate more value because the necessary labor time embedded in each commodity has been reduced.

Capitalist Methods for Increasing Productivity

Capital raises productivity through two main channels: the introduction of machinery and the process of subsumption. Both aim to bring more output into the same or a smaller amount of labor time, thereby expanding surplus value.

Objects and Types of Subsumption

Subsumption targets three objects: nature, the labor process, and laborers themselves.
- Ideal subsumption is the initial concept of putting these objects to work for capital.
- Formal subsumption imposes external control via rules, timings, and signs that dictate how work is performed.
- Real subsumption internalizes control; workers self‑discipline, and their desires are aligned with capital’s ends.
- Total subsumption is a hypothetical state where life and capital become indistinguishable.

Subsumption reorganizes natural parameters such as free time into capital’s parameters like “time off,” and it makes capital appear as the source of all goods and pleasures.

Effects of Subsumption

By bringing elements under capitalist control, subsumption converts natural and social relations into parameters of valorization. Capital thus presents itself as the origin of all commodities, leisure, and satisfaction, masking the underlying appropriation of labor and nature.

The Immediate Production Process

The immediate aim of production under capitalism is the creation of value. Each act of entering the factory reproduces the capital system that summoned the worker. The means of production may seem to employ the worker, while “dead labor” (the accumulated past labor embodied in tools and machines) absorbs living labor. All labor becomes wage labor, but not all wage labor qualifies as productive labor in Marx’s technical sense.

Productive vs. Non‑Productive Labor

Productive labor directly creates exchangeable commodities and generates surplus value for the capitalist. Non‑productive labor—such as domestic work or personal projects—has worth but does not enter the exchange system and therefore does not produce surplus value.

Alienation under Formal Subsumption

Under formal subsumption the product is taken away from the producer and transferred to the capitalist, standing as an external obstacle to the worker. The labor process itself is also removed from the worker’s control, depriving them of intelligent engagement with their work. This double alienation makes workers particularly unfree.

Efficiency, Management, and Psychology

Taylorism and scientific management sought to systematize labor and boost efficiency through precise timing and supervision. Industrial‑organizational psychology emerged to manage both efficiency and job satisfaction. “Speed bosses” timed workers’ movements in minute increments, while “soldiering” (inefficient pacing) was curbed through incentives. Psychology was employed to create an internal boss, fostering an “optimum balance” of satisfaction and dissatisfaction that aligns workers’ desires with capital’s goals.

Shift toward Real Subsumption

In real subsumption control becomes internalized; workers self‑discipline and experience a form of job satisfaction that serves political control. Psychological techniques are used to shape desires, producing a state where satisfaction and dissatisfaction are calibrated to keep labor productive.

Technical Aspects of Surplus Value (Chapter 15)

Three variables govern surplus value: the extensive magnitude of labor (duration), the intensive magnitude (intensity), and productivity (output per input). With extension and intensity held constant, higher productivity lowers the value of each product but does not increase total value. When productivity rises, the value of labor power can fall if the cost of subsistence drops, allowing surplus value to rise. The cost of labor power and surplus value move inversely; they cannot rise or fall together. Causality for increasing surplus value flows from either higher productivity (which can lower labor‑power cost) or from greater extension/intensity of work.

Critique of Capitalist Efficiency

Capitalist efficiency is measured by the ability to produce surplus value, not by the preservation of nature or human well‑being. The system seeks a mode of production that avoids waste of natural resources while still extracting maximal surplus, but the drive for profit often conflicts with respect for human life and ecological balance.
