They differ in where they come from, who supplies them, what they are paid, and whether they can be made more of. Comparing them on those four points is what makes the classification useful rather than a list of names.
| Basis | Land | Labour | Capital | Entrepreneurship |
|---|---|---|---|---|
| Origin | Gift of nature — soil, forests, water, air, sunlight, minerals, oil, natural gas | Human beings, through physical and mental effort | Human-made; itself produced earlier, then used to produce again | A person’s idea, judgement and willingness to bear risk |
| Can more be made? | No — its total supply is fixed and it can be degraded | Yes, and its quality can be raised through education, training and health | Yes — by saving and investing | Rare; it can be encouraged but not manufactured |
| Mobility | Immobile — a plot, a mine or a river cannot be shifted | Mobile, but people move reluctantly | Money moves instantly; machinery moves with cost | Mobile — the entrepreneur goes where the opportunity is |
| What the book says it is paid | Rent, if not purchased outright | Fair compensation for their labour | Interest to a lender; a dividend to shareholders | Whatever is left — profit, and no guarantee of any |
| Risk carried | None by the owner if rent is paid | Little — wages are due whether or not the goods sell | Interest is due regardless | All of it. The entrepreneur is paid last, or not at all |
The difficulties in classifying — and they are real ones.
- Inputs that sit on a boundary. Is electricity land or capital? It is produced by people, but from coal, water or sunlight. Is storage space land or capital? The site is land, the building on it is capital, and one rent covers both.
- Raw materials that have already been worked on. Fresh produce began as land, but the crate of vegetables delivered to the restaurant already contains labour, a vehicle and fuel. Where do you stop tracing it back?
- Labour or human capital? The report lists “knowledge and skills to handle mobile components” as an input. That is not the effort of labour; it is the human capital behind it. The book keeps them separate but our table did not have a column for it.
- One person playing three parts. The owner of a small grocery shop supplies the capital, does the labour, and is the entrepreneur — all at once. In a large company these are three different sets of people, which is why the classification looks cleaner there.
- Money is not capital by itself. Money in a bank produces nothing; it becomes capital only when it is turned into equipment, stock or a shop.
