On the Principles of Political Economy, and Taxation

In the winter of 1815, with Britain starving under the Corn Laws that kept bread prices artificially high, a self-taught stockbroker and member of Parliament wrote a book that would invent modern economics. David Ricardo's masterwork attacks the protectionist tariffs crushing the poor while articulating something more radical: the principle of comparative advantage, proving that nations gain from trade even when one produces everything more efficiently. This isn't a dry theoretical text. It emerges from Ricardo's moral fury at landowners enriching themselves while laborers starve, and his dazzling argument that labor, not land or money, determines value. He maps the economy as a battlefield between three classes, landlords, capitalists, workers, whose interests fundamentally conflict over every bushel of wheat. The book reads like a polemic dressed in arithmetic. Marx built on it; Mill refined it; every subsequent debate about trade, rent, and inequality circles back to Ricardo's founding move. For readers who want to understand where our economic world came from, and why trade wars and housing costs still feel so fought-over, this is the source code.
