Any product – grain, a table or a smartphone – consists of raw materials extracted from nature and the labour invested in its production. The table is made of wood or plastic; the smartphone contains more than a hundred different alloys and plastics. The production of goods or services requires energy, which is produced by the physical effort of humans or animals, or by burning coal or gas. Unlike labour, which conforms to rules and lends itself to generalisations, raw materials have always been a matter of chance discoveries, distant journeys, successful ventures or, alternatively, disasters. The ambitions of rulers, the caprices of nature, the mistakes of scientists, the cupidity of managers, all culminated in the sovereigns finding themselves tête-à-tête with their mines, fields, boreholes, while the intermediaries were sacrificed.
An economy that deals in metals is different from an economy based on textiles, which is different again from an economy depending on oil. In the age of empires, each of the great economic machines concentrated on a particular form of natural resource. Embedded within the culture of its time, such a

Economists have long been writing about the fact that natural resources are more like assets than goods. The price of a barrel of oil or an ounce of gold does not depend on the cost of its extraction any more than the value of an asset depends on the salaries of a bank’s employees. Other factors define the price of gold: the rate of inflation, festivals in India, the threat of war. In contrast, the price of goods reflects the labour of engineers, workers, retailers and researchers. Labour is law-abiding; nature is contingent and, sometimes, rebellious. Unlike labour or knowledge, natural resources have a habit of running out. Extraction begins with peak productivity: the sea teems with fish, grain grows effortlessly, gold gleams in creeks, oil gushes in fountains. At the start of any extraction cycle, there is an Eldorado. As the years go by the earth loses its fertility, the mines become ever more dangerous, and the boreholes ever deeper. The fish in the sea and the trees in the forest disappear as a result of ‘the tragedy of the commons’: people exhaust a precious resource, considering it limitless because it doesn’t belong to any one individual. 6 But even an individual owner exhausts his land, which is the reason for agricultural techniques such as crop rotation. Owned privately or publicly, fountains of oil dry up and the oil has to be pumped out, while adjacent oilfields are usually less productive.
