Georgism holds that people rightfully own what they produce through their own labour, but that the value of land — which no one produced — belongs to the whole community. Its signature proposal is the single tax: capture the economic rent of land through a land-value tax, and abolish taxes on labour, buildings, and capital.
The argument begins from a puzzle that gives Henry George's Progress and Poverty (1879) its title: why does poverty deepen even as material progress advances? His answer is that landowners quietly capture the gains of progress as rising rent — a new railway or a growing city raises land values without the owner lifting a finger — so the fruits of productivity flow to those who merely hold well-placed sites rather than to those who work or invest.
The book was a nineteenth-century phenomenon, outselling almost everything but the Bible in its decade, and it left durable marks: land-value taxation in parts of Pennsylvania, Denmark, and Taiwan, the design of the board game later sold as Monopoly (invented to teach George's lesson), and a steady influence on urban economists who still regard the land tax as close to an ideal, distortion-free levy.
The position is unusually hard to place because it is at once radical on land and orthodox on markets, and it has been embraced by free-marketeers (who love a tax that doesn't distort production) and socialists (who see common ownership of the earth) alike. That dual character is definitional, not confusion.
Its critics argue the single tax could not raise enough revenue for a modern state, that assessing pure land value apart from improvements is harder than George assumed, and that in an economy dominated by finance and intellectual property, land is no longer the master key to inequality it was in 1879.
It is frequently dismissed as a single-issue crank theory, which undersells it: its core distinction — between wealth that is produced and wealth that is merely captured through ownership of a scarce natural asset — is a serious and recurring idea in economics.
Deliberately wide: fully market-side on labour and capital, fully collective on land value, and the axis forces a single answer where the doctrine gives two.
Sits astride the midline: liberty in exchange, equality in access to natural opportunity, with neither given clear priority.
Radical in aim but strictly gradualist in means — a change of tax base pursued through ordinary legislation.
Universalist: the claim to the earth's value is owed to everyone, and the community it invokes is thin and civic rather than ethnic.
Individual as the unit of concern, with a firm positive duty owed by those who hold land to everyone excluded from it.
