enry George is best remembered as a proponent of the “single tax” on land. The government should finance all of its projects, he argued, with proceeds from only one tax. This single tax would be on the unimproved value of land—the value that the land would have if it were in its natural state with no buildings, no landscaping, and so on. George’s idea was not new; it was largely borrowed from David Ricardo
, James Mill, and John Stuart Mill
In his heyday Henry George was very popular, with his ideas inspiring passionate debate among young intellectuals. After George published Progress and Poverty
in 1879, a political movement grew in the United States around his work. He later narrowly missed being elected mayor of New York.
Most taxes, noted George, stifle productive behavior. A tax on income reduces people’s incentive to earn income, a tax on wheat would reduce wheat production, and so on. But a tax on the unimproved value of land is different. The value of land comes from two components, its natural value and the value that is created by improving it (by building on it, for example). The value of a vacant lot in its natural state comes not from any sacrifice or opportunity cost
borne by the owners of the land, but rather from demand
for a fixed amount of land. Therefore, argued George, because the value of the unimproved land is unearned, neither the land’s value nor a tax on the land’s value can affect productive behavior. If land were taxed more heavily, the quantity available would not decline, as with other goods; nor would demand decline because of land’s productive uses. By taxing the whole of the value of unimproved land, the government would drive the price of land to zero.
George was not simply trying to design a system of taxation devoid of untoward consequences; he felt that virtually all economic problems arise from “the fact that the land on which and from which all must live is made exclusive property of some.” His goal was nothing less than to make all land common property, but he realized that, “[i]t is not necessary to confiscate land; it is only necessary to confiscate rent.”
George was right that other taxes may have stronger disincentives, but some economists now recognize that the single land tax is not innocent, either. Site values are created, not intrinsic. Why else would land in Tokyo be worth so much more than land in Mississippi? A tax on the value of a site is really a tax on productive potential, which is a result of improvements to land in the area. Henry George’s proposed tax on one piece of land is, in effect, based on the improvements made to the neighboring land.
And what if you are your “neighbor”? What if you buy a large expanse of land and raise the value of one portion of it by improving the surrounding land. Then you are taxed based on your improvements. This is not far-fetched. It is precisely what the Disney Corporation did in Florida. Disney bought up large amounts of land around the area where it planned to build Disney World, and then made this surrounding land more valuable by building Disney World. Had George’s single tax on land been in existence, Disney might never have made the investment
. So even a tax on unimproved land can reduce incentives. As certain as George was that “the value of land can always be readily distinguished from the value of improvements,” he was aware that over a long period some improvements blend with the natural state of the land and can be “considered part of the value of that land.” George was also aware that “[a]bsolute accuracy is impossible in any system, and to attempt to separate all that the human race has done from what nature originally provided would be as absurd as impracticable.”
argued that the entire value of land is the value of its improvements because of a need to discover it and bring it into production.
Zachary Gochenour and Bryan Caplan have pointed out that while the surface value of land is more apparent, especially for farming purposes, many lands have hidden natural resources, such as gold, water, and oil. These resources require investment on the part of owners to discover and produce. “Information about the land can be considered an improvement in its own right.” To tax the entire, or even a large, value of the mineral resources would create enormous disincentives for exploration and production. Objections aside, Henry George may have been arguing for what is really the least offensive tax. As Milton Friedman
said almost a century after George’s death: “In my opinion, the least bad tax is the property tax on the unimproved value of land, the Henry George argument of many, many years ago” (Mark Blaug. Economica,
New Series, 47, no. 188  p. 472).
Henry George was also a passionate advocate of free trade
and opponent of protectionism
. He saw clearly that protectionism is a misleading term for barriers to trade and identified whom “protectionism” hurts. George wrote:
To every trade there must be two parties who mutually desire to trade, and whose actions are reciprocal. No one can buy unless he can find some one willing to sell; and no one can sell unless there is some other one willing to buy. If Americans did not want to buy foreign goods, foreign goods could not be sold here even if there were no tariff. The efficient cause of the trade which our tariff aims to prevent is the desire of Americans to buy foreign goods, not the desire of foreign producers to sell them. Thus protection really prevents what the “protected” themselves want to do. It is not from foreigners that protection preserves and defends us; it is from ourselves.
