Smith’s revolution in what wealth <em>is</em>: not a nation’s hoard of gold but the productive labour of its people - and the labour theory of value that idea launched.
Smith opens The Wealth of Nations with a quiet revolution. The reigning doctrine of his age, mercantilism, held that a nation’s wealth was its store of gold and silver - that to grow rich, a country must accumulate bullion by exporting more than it imports. Smith swept this away. The real wealth of a nation, he argued, is not its hoard of precious metal but its capacity to produce the goods and services people actually use - the ‘annual produce of its land and labour.’ Gold is merely a token; the true source of national wealth is the productive labour of the people, and the things that labour makes. A nation is rich not when it has much gold, but when it produces much that people need and want.
If wealth comes from productive labour, then the key to growing rich is making labour more productive - and Smith’s great answer is the division of labour. He gives three reasons it multiplies output so dramatically. First, dexterity: a worker who repeats one narrow task all day becomes extraordinarily skilful and fast at it. Second, time saved: switching between different tasks wastes time, and specialisation eliminates that switching. Third, machinery: workers focused on a single operation are far more likely to invent or improve tools and machines that aid that specific task. By these three routes, dividing a complex job among many specialised hands raises output not by a little but by orders of magnitude - the pin factory where ten specialised workers make tens of thousands of pins a day, where one generalist could make only a handful. And crucially, Smith adds, the division of labour is limited by the extent of the market: you can only specialise as finely as the size of your market allows you to sell. Bigger, freer markets permit deeper specialisation, which produces more wealth - the link between his theory of production and his case for free trade.
Smith’s labour theory of value rests on a deceptively simple thought: the real cost of anything is the effort it takes to get it. Money prices fluctuate; gold and silver are themselves variable in value; but labour - the toil and trouble a thing costs - is, Smith argues, the ultimate and most stable measure of what things are really worth. When you buy something with money, you are really buying the labour of others; money is just the intermediary. So the true price of every thing is ‘the toil and trouble of acquiring it,’ and labour is ‘the real measure of the exchangeable value of all commodities.’ This idea does important work for Smith: it locates the source of value in human productive effort rather than in nature or in money, and it provides (he hopes) a stable yardstick for comparing wealth across times and places. But Smith was too careful a thinker not to see the complications. Once production requires not just labour but also capital (tools, materials) and land, the value of a good must also pay profit to the capitalist and rent to the landlord - so price is no longer simply proportional to labour. Smith wrestled with this without fully resolving it, leaving a tension that his successors would seize on: Ricardo trying to rescue a rigorous labour theory of value, and Marx turning the gap between the value labour creates and the wage labour receives into the foundation of his theory of exploitation.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that Smith located the wealth of a nation in its productive labour and groped toward a labour theory of value. Explain that shift, and the puzzle of value it opened, in your own words.
