The Wealth of Nations

What actually makes a nation rich? Against the reigning belief that wealth is hoarded gold and a favourable balance of trade, Smith relocates it in the yearly produce of a people's work.

The reigning wisdom held that a nation grew rich by hoarding gold, selling more abroad than it bought, and steering trade with tariffs, monopolies and colonies — the mercantile system. Smith spent much of a very long book taking it apart. Wealth, he argued, is not the gold in the treasury but the annual produce of a nation's labour, and that produce grows fastest when labour is divided finely and left free to seek its most profitable use. This reframing turns economic policy from a contest over bullion into a question of how to raise a society's real output, and it armed a century of argument for free trade.

Why does splitting work into small tasks make a people so much more productive, and can private self-interest really serve the public good? Smith opens with a pin factory and coins a famous phrase.

Smith's pin factory, where ten men splitting the work make what one alone never could, opens the argument: the division of labour is the great engine of productivity. Left free, labour and capital flow to their most profitable use, and here appears his most famous phrase — the invisible hand, used exactly once, for the way private self-interest can serve an end no one intended. The claim is narrower than its later fame suggests: not that markets are always right, but that under the right conditions individual gain can add up to public benefit, coordinated by no central design.

Was Smith the prophet of leave-it-alone his name now invokes? The book itself is warier, distrusting merchants and insisting the state act where the market would grind people down.

Smith was warier than his later admirers. The same book that argues for free trade distrusts merchants who conspire against the public and raise prices, and it insists the state educate the poor whom the endless repetition of divided labour would otherwise dull and deaden. His free trade is aimed against monopoly and privilege, not against all public action, and he expects government to supply what markets will not. Reading him as a pure apostle of self-interest and minimal government flattens a thinker who watched commercial society closely enough to name its costs as sharply as its benefits.
