>>489299The broadest interpretation of Georgism is the 'single tax' on unimproved land value. IE no taxes on labor, no taxes on improvements, no taxes on sales, but taxes on raw land value at high rates to disincentivize land speculation and encourage productive land use. This is the main uniting Georgist idea. This principle includes taxation of natural resource extraction, and has been additionally proposed to include taxing pollution as an externality, and, later, there have been proposals to include taxation of other forms of economic rentseeking like intellectual property.
The second broadest idea is the 'citizens' dividend,' which proposes that the value of land taxation be redistributed to the general public universally. Geolibertarians advocate for a very small state where this system of distributing revenue from land wealth is the primary public service function of the state.
Thirdly, George advocated for the nationalization of natural monopolies.
