How Confusing Capacity with Value Breaks Socialist Economics
An OP in this sub recently started with someone making the early claim that "value is finite." What followed wasn't an explanation of value, but a description of physical production capacity limits. The author pointed out that society has a limited number of workers, a limited number of hours in a day, and a limited stock of tools. He credited the Labor Theory of Value (LTV) for the premise.
It is an interesting confusion because it exposes the core blind spot of Marxist economic thought. It treats value as if it's merely a synonym for physical production limits, with labor acting as the sole social input. That skips the majority of the actual economic story.
Value in any meaningful sense isn't a measurement of physical factory output. Value is about us: what we want as human beings, what we prioritize, and what we are willing to surrender to get what we don't have. Production capacity describes what is physically feasible. Value, on the other hand, describes why anyone cares enough to produce it in the first place.
The entire socialist narrative that production is (roughly) a value-generating engine with labor as the sole meaningful human input turns economics on its head. Labor doesn't magically inject an invisible substance called value into physical objects. Labor is a cost. It is an expenditure of scarce, finite human time and effort. We don't value goods because labor went into them. Rather, we only expend labor when we anticipate that the finished good will be valued enough at the margin to justify the sacrifice.
When challenged on this, socialists invariably try to cram the missing half of the equation into the words "socially necessary." But that is an answer that isn't an answer. What makes labor socially necessary? The market. How does the LTV explain that mechanism? By declaring after the fact that whatever didn't sell, whatever failed to clear, or whatever had its price collapse simply "wasn't socially necessary". It uses the outcome of market exchange to define the inputs retroactively, then pretends the input was the causal driver all along. It doesn't explain how society coordinates priorities. It just labels the result, draws an arrow to labor, and claims economics has been explained.
Every single person possesses scarce resources: our time, our energy, our specialized skills, our tools, and our savings. We can deploy those resources in an infinite number of combinations. Private property is simply the institutional recognition that individuals can own, maintain, and trade those resources, and the tools used to produce further things, in a decentralized network. It is the mechanism through which millions of separate individuals figure out what society actually wants, what trade-offs are worth making, and how to allocate scarce effort without relying on a central authority to guess on everyone's behalf.
To wish that entire coordination mechanism away requires a deeply reductionist view of the world. Reducing the complex web of human evaluation to a factory capacity ledger, waving away the hard problem of social valuation with the words "socially necessary," and then concluding we should abolish private property, is just an economically crippling dead end.
