Private Property, Liberalism, and Human Flourishing

Private property enables individuals to pursue happiness through their own free choices. It also shields our individual and institutional projects from arbitrary power

By Alexander William Salter. Excerpt:

"For thousands of years, human living standards were basically stagnant: in inflation-adjusted terms, world GDP per capita fluctuated around $1,500 per year. In the nineteenth century, commercial innovations, including widespread protection for private property rights, gave rise to the Industrial Revolution. This resulted in history’s only sustained reduction in human poverty. In the United States, for example, GDP per capita in 1800 had risen to approximately $2,500 per year. It more than tripled over the next century, to $8,000 per year. Near-continuous economic growth yielded a figure of nearly $50,000 per year by 2000, and nearly $70,000 today. 

Other western nations that embraced capitalism enjoyed similar increases in material prosperity. Asian nations, such as Japan, South Korea, and (more recently) China, have also benefited from embracing private property rights. These successes strongly suggest there is something universal about the relationship between private property and economic wellbeing. It’s not culturally contingent.

Our historically unprecedented level of wealth only exists because private property enables an extensive division of labor. Exponential gains in per capita GDP would be impossible, and indeed, they have never occurred in a sustained way without productivity-enhancing specialization and trade. This decentralized process for creating and exchanging wealth requires coordination. As Ludwig von Mises recognized, private property rights are vital. Without private property, trade and markets could not exist. And without markets, there would be no market prices—critical indicators of resource value in varying lines of production. Profit and loss accounting could not be meaningful without prices, meaning businesses would have no reliable way to ascertain whether they were satisfying consumer wants. It is the system of market prices, adjusting in response to supply and demand changes, that gives commercial society its unique power to create wealth. Private property is the keystone: it holds the whole market edifice together.

The greatest benefits of the price system often emerge during times of turbulence. When war between the United States, Israel, and Iran choked off shipping through the Strait of Hormuz in early 2026, the price of crude oil spiked. Refiners, shippers, and drillers across the world rerouted and searched for new supply, responding to the price shock without needing to know anything about geopolitical stakes or possible resolutions. The price carried the knowledge so that they did not have to. 

It may seem strange to use hardship to illustrate the importance of private property and prices. But in fact, it reveals why they matter. Oil became scarcer as a result of the war. That made everyone in the world poorer. Nothing can change that so long as the conflict continues. Instead, the price system allows economic actors oceans apart to find and pursue least-cost adaptations. Non-market and non-price rationing work poorly on this scale. At least with property and prices, we know where we need to change.

Private property buttresses the market process in several other ways. Building on Mises, F. A. Hayek realized that prices allowed households and firms to benefit from each other’s private and often tacit information. The price system, founded on private property, thus functions as a powerful communication and feedback system. Ronald Coase argued that market values for owned resources allowed conflicting parties to resolve their disputes by bargaining. Armen Alchian, William Allen, and Harold Demsetz pointed out that firms’ property rights to their residual income aligned the interests of producers with consumers, and that the firm itself, as an organizational form, was possible only because private property allowed for the necessary contractual structures. The immense productive capacity of contemporary capitalism, which we often take for granted, relies on practices rooted in private property.

Human flourishing obviously depends on more than material wealth. “Man does not live by bread alone.” Yet he does need bread to live. The material abundance created by markets keeps us fed, sheltered, clothed, literate, healthy, and entertained. It also provides the means for us to pursue meaningful artistic, intellectual, and moral projects. Private property is the reason we can have all of these things."
