All that has come down to us is Cantillon’s treatise
Labour could increase the value of a natural product many times over. For Cantillon, this is a miracle which needs investigating. He was surprised to learn that, in the steel spring inside an English watch, the relation of the cost of the material to the cost of the work was one to a million. His method celebrated the superiority of labour over land. If one country exchanges its labour for the raw materials of another country, then the first country will have the advantage in this trade, since it maintains its people at the expense of that other country. As an example, Cantillon puts forward the trade between Paris and Brussels: lace is exchanged for champagne for the sum of 100,000 ounces of silver per year. He calculates that the harvest of a single acre of Flemish flax, with value added by the Brussels lace-makers, is equal in value to the wine from 16,000 acres of French vines. Thanks to this exchange, many people could live on every acre of Flemish land, doing other things – shipbuilding, military service or scholarly work – and buying food from Burgundy or elsewhere. The more productive the labour, the less land it needs for creating wealth. Thousands of acres of French land went to Brabant along with the barrels of wine every year, just as if France had temporarily lost this land in a war. From Brussels, Cantillon went on to examine the problems of Eastern Europe. If a Polish landowner is also fond of Brussels lace, it will cost him a sixth of the income that he receives from selling the grain grown on his estate; if he is fond of wines from Burgundy, he will pay another sixth of his income for them. In exchange for the product of 1 acre of land in Brabant and 1,500 acres of land in Burgundy, the Polish landowner will give grain harvested on hundreds of thousands of acres of his own land. In this way Holland and Flanders maintain half of their population, exchanging the fruits of their labours for products from a foreign land. For any single product, the higher the value of human labour and the lower that of raw material, the better it is for the economy that trades in this product. 12
Cantillon looked at energy and mines as well. England prospers thanks to its deposits of coal, he wrote. He calculates that English coal saved several millions of acres which would otherwise be needed to grow timber – those very same acres which 300 years later would be called ‘ghost acres’. Some mines create wealth, wrote Cantillon, others lose money. The more gold or silver the Spanish mines extract, the more meat the Spaniards will eat and the more luxuries they will buy. The higher the value of land in a particular country, the higher the prices of all other goods. Moreover, explains Cantillon, wages don’t rise in line with prices, because they had been fixed by contract. While the entrepreneurs and landowners are counting their profits, it will become clear to the workers that their wages buy fewer and fewer goods. Some of them will tighten their belts, others will emigrate. Exacerbating inequality, the wealth of the mines has a ruinous effect on farms and factories. A part of the new money will be spent on importing foreign goods, and the country’s own industry will go into decline. Poverty and neglect will be evident everywhere. Cantillon is describing the mechanism of the ‘Dutch disease’ hundreds of years before it was identified.
