Smith distinguishes between labour that fixes itself in a vendible commodity — something that can be stored, exchanged, and sold after the work is done — and labour whose value perishes in the moment of its production. The first is productive. The second is unproductive. This distinction determines how resources compound or deplete over time.
- Productive LabourLabour that adds to the value of the subject on which it is employed — a manufacturer adding value to raw material, a craftsman producing a finished good. The value produced exceeds the wages paid. The surplus becomes the profit that funds further accumulation.
- Unproductive LabourLabour whose product has no vendible value after the work is done — domestic servants, armies, legal professionals, clergy. Their services are consumed the moment they are performed. Nothing remains that can be sold or stored. The resources spent on them are consumed, not invested.
- The ImplicationNations and enterprises that direct a large proportion of their stock toward unproductive labour deplete their capital over time. Those that direct it toward productive labour accumulate. The rate of accumulation or depletion is determined by this proportion.
Strategic Application
Audit every expenditure of force and material: does it produce something vendible — a durable gain, a structural position, a compounding advantage? Or does it produce a service that is consumed the moment it is rendered? Both may be necessary. But the proportion between them determines whether the enterprise accumulates or depletes over time.
