“Landlords love to reap where they never sowed.” – Adam Smith
When Smith wrote those words in The Wealth of Nations, the global economy was barely recognisable compared to today. Industrialisation had yet to transform production, the modern financial system did not exist, and the world’s population was only a fraction of what it is now. Yet despite two centuries of extraordinary economic progress, one problem remains stubbornly familiar: housing.
Across many advanced economies, housing affordability has deteriorated significantly. In major cities across Europe and North America, rents and house prices have grown far faster than wages. Younger generations increasingly find themselves locked out of property ownership, while those who already own housing often see their wealth expand rapidly.
This raises a difficult question that echoes Smith’s original critique. Are landlords providing valuable services to society, or are they primarily capturing economic rents generated by broader social and economic forces?
Housing as an Economic Asset
Housing occupies a unique position in modern economies. It is both a basic human necessity and one of the most important financial assets individuals can own. People need somewhere to live, yet property also serves as a store of wealth, an investment, and, increasingly, a vehicle for financial accumulation.
In many developed economies, housing now represents between 40 and 70 % of total household wealth, according to data from organisations such as the OECD and IMF.
This dual nature creates tension. When housing primarily serves its function as shelter, markets tend to focus on providing adequate supply and affordability. But when housing becomes an investment asset, incentives shift. Rising prices benefit existing owners, even as they make housing less accessible for others.
Understanding this tension requires stepping back into the history of economic thought.
Classical Critiques of Landlordism
Long before modern housing crises, classical economists were already uneasy about the economic role of landlords.
Adam Smith
Smith viewed landlords as a peculiar economic class. Unlike merchants or manufacturers, who generated income through productive activity, landlords often earned income simply by owning land. As economic development increased the value of land, landlords could benefit without necessarily contributing to that growth.
Smith’s famous observation that landlords “love to reap where they never sowed” captured this concern. For him, landowners were often beneficiaries of broader social progress rather than the drivers of it.
David Ricardo
Smith’s intuition was later formalised by David Ricardo in his theory of economic rent, outlined in On the Principles of Political Economy and Taxation.
Ricardo argued that as populations grow and economies expand, demand for land increases. Yet the supply of land is fixed. This scarcity allows landowners to capture what economists call economic rent, where income derived not from productive activity but from the inherent scarcity of a resource.
In this framework, rising land values are not primarily the result of landlord effort. Instead, they reflect broader economic growth and increasing demand for space.
Henry George
Perhaps the most famous critique of landlordism came from Henry George in his influential book Progress and Poverty.
George observed a puzzling phenomenon in rapidly industrialising societies: as economies grew richer, poverty often persisted or even worsened. His explanation centred on land.
Because land is fixed in supply, its value rises as cities grow and economic activity increases. Crucially, George argued that this increase in value is created by society through infrastructure, population growth, and economic development, rather than by the landowners themselves.
To address this imbalance, George proposed a land value tax, which would tax the unimproved value of land rather than labour or capital. The idea was that landowners should return to society the value it had created.
The Return of the Rentiers
For much of the twentieth century, the concerns raised by classical economists seemed less pressing. Industrial capitalism shifted wealth toward productive capital.
However, recent economic research suggests that the classical worries about land may be re-emerging.
Thomas Piketty
In Capital in the Twenty-First Century, Thomas Piketty argued that modern capitalism may naturally generate rising inequality when the rate of return on capital exceeds economic growth. Those who own capital accumulate wealth faster than those who rely primarily on labour income.
Housing plays a significant role in this dynamic. For many households, property is their largest asset, meaning that rising house prices can dramatically increase wealth inequality between owners and non-owners.
Matthew Rognlie
Further research by Matthew Rognlie reinforces this idea. In his paper Deciphering the Fall and Rise in the Net Capital Share, Rognlie analysed changes in the share of income going to capital in advanced economies.
His findings were striking: much of the increase in capital’s share of income was driven not by corporate profits or industrial capital, but by housing rents.
In other words, rising income from property has played a central role in the changing distribution of wealth.
Brett Christophers
This trend has led some scholars to argue that modern economies are increasingly characterised by rentier capitalism. Brett Christophers, in Rentier Capitalism, describes how profits are increasingly generated through the ownership of scarce assets rather than through productive innovation. Housing is the clearest example. Owning property in a growing city can generate substantial wealth even without additional productive activity.
Empirical Evidence of Housing Financialization
The theoretical concerns raised by economists are reflected in several observable trends.
First, housing has become an increasingly dominant form of wealth. As noted earlier, it represents a large share of household wealth in developed economies. Second, many countries have experienced a rapid expansion of buy-to-let ownership since the 1990s, particularly in markets such as the United Kingdom. Third, institutional investors have entered housing markets on a larger scale since the 2008 global financial crisis. Private equity firms, real estate investment trusts, and other large investors have acquired significant portfolios of residential property. Finally, housing prices in many major cities have grown substantially faster than wages. In cities such as London, New York, and Toronto, housing affordability has become a central economic and political issue.
These trends suggest that housing is increasingly treated as a financial asset rather than simply a place to live.
Counterarguments
Despite these concerns, it would be misleading to portray landlords purely as economic parasites. Rental housing performs important functions in modern economies. First, renting provides flexibility and mobility. Students, migrants, and young professionals often rely on rental housing because purchasing property may be impractical or impossible at certain stages of life. Second, landlords perform genuine economic services. They maintain properties, manage tenants, and absorb financial risks such as vacancies and repair costs. Third, some economists argue that housing crises are primarily driven by supply constraints, such as restrictive zoning laws and slow planning systems. In this view, landlords may benefit from rising prices, but they are not the underlying cause. These arguments highlight the complexity of housing markets.
The Landlord Paradox
This complexity gives rise to what might be called the landlord paradox. Landlords can simultaneously provide a useful economic service while benefiting from scarcity that they did not create.
Rental housing is necessary in any functioning economy. Yet when housing supply is constrained, property ownership can become a powerful mechanism for capturing economic rents generated by broader social development. The problem, therefore, may not be landlords themselves, but a housing system that increasingly rewards ownership of scarce assets.
Policy Solutions
Addressing housing inequality is far from straightforward, and economists continue to debate potential policy responses.
One widely discussed idea is the land value tax, inspired by Henry George. Because land cannot be moved or hidden, taxing its value is often seen as economically efficient. Such a tax could reduce speculative investment and encourage more productive use of land.
Another approach focuses on increasing housing supply. Planning reform, zoning changes, and faster construction approvals could help reduce scarcity in high-demand areas.
Some policymakers have also proposed limits on large-scale institutional ownership of housing, particularly in markets where corporate investors are rapidly acquiring residential properties.
Finally, public housing models offer another potential solution. Cities such as Vienna maintain large social housing sectors that provide stable and relatively affordable rental housing for residents.
Each of these approaches involves trade-offs, and no single policy is likely to solve housing challenges on its own.
Conclusion
More than a century ago, Henry George warned that societies could become wealthier while poverty persisted if land rents were privately captured. Today, the global economy is vastly richer than in George’s time. Yet the tension he identified remains visible in modern housing markets. Property ownership remains one of the most reliable paths to wealth, while those without access to property often face rising housing costs and limited opportunities to build assets.
Perhaps the real question is not whether landlords are inherently good or bad. Instead, it may be whether modern economies should continue to reward wealth accumulation through ownership of scarce land, or whether policy should encourage a greater focus on productive investment and broader access to housing.
