Henry George (1839–1897) was an American economist best known in the provided context for his 1879 bestseller Progress and Poverty. The passages describe him as the originator of Georgism, also called the single-tax theory. In this view, the products created by human labor and capital should belong entirely to the individual who produced them, while economic rent derived from shared resources such as nature and land should be returned to society as a whole.
According to the context, George’s ideas argued that private ownership of land and the unearned income generated by rising land values helped lock in urban inequality and poverty. On that basis, Georgists strongly advocated abolishing income tax and consumption tax, and instead imposing a tax only on the site value of land, known as the Single Tax. The passages place George’s thought within the social conditions of late-19th-century America, including rapid industrialization, population concentration in cities, inequality, and rising land prices.
The context also notes that Henry George’s ideas influenced the ideological background of The Landlord’s Game. Beyond these points, the provided material does not give additional biographical detail.
