The Increment

Ricardo had drawn the mechanism and walked on, leaving the moral question lying in the field. It was picked up, two generations later and half a world away, by a man with no university behind him — a printer's case, a few hard years at sea, a journalist's eye — who had watched the thing happen in front of him. Henry George came to San Francisco as a young man and saw California convulse with growth: the railroad arriving, the population multiplying, fortunes erupting from the bare ground. And he saw, in the same streets and the same years, want and squalor deepen exactly as the wealth piled up. The two facts sat side by side and would not be reconciled by anything he had been taught. In 1879 he published the book that tried to reconcile them, and it made him, for a season, one of the most famous men alive.¹

The puzzle in its title — Progress and Poverty — was the puzzle of the century. The nineteenth century had believed, with some reason, that material progress would lift the poor: that growing wealth and advancing technique and rising productivity would raise the floor beneath the worst-off. And in the aggregate the wealth was indeed swelling astoundingly. Yet the poverty would not lift. In the most advanced cities, amid the greatest accumulations, festered the most abject slums; progress and poverty advanced together, and the advance of the one seemed somehow to feed the other. Why should the richest societies harbour the bitterest want? Why did the tide that raised so many vessels strand so many others on the bottom? George named this the great enigma of the age and set out to find its cause — and found it, he believed, in the ground.²

His answer was Ricardo's law, taken with deadly seriousness and followed to its end. The gains of progress, George argued, are captured by the rent of land. As a society advances — as its people grow more numerous, its arts more cunning, its capital deeper — the produce it can wring from the earth swells. But that swelling produce does not raise wages or the return on capital; it is intercepted, on its way, by rent. The growth lifts the demand for land, and so its rent; and because the land is fixed, the rent simply rises to absorb the gain, leaving the labourer and the capitalist where they were — and often worse, for as rent climbs, the margin at which they must work recedes, and the share left to be divided between them thins.

Here was the resolution of the paradox. Progress does not fail to produce wealth; it produces it in floods. It fails to distribute it, because a third party stands at the gate — the landowner — and takes the increase as it goes by. The more the society produces, the more there is for rent to claim, and the more it claims. The worker on the advancing frontier of a rich country runs faster and faster and stays in the same place, because the ground he runs on is owned, and its owner collects the speed.³

And now the moral charge, which is the book's true engine and the reason it set fire to a generation. The rise in the value of land — the swelling rent that intercepts the gains of progress — is created by no act of the landowner. It is created by the community.

John Stuart Mill had given the thing its name a few years earlier and called it the unearned increment, and had proposed, gently, to tax its future growth for the public benefit. George took the name and removed the gentleness.⁴ For if the increment is unearned — if the value of land is the community's creation — then to let it fall into private hands is to let a few collect a private tax on the presence and progress of everyone else. The landowner, in George's accounting, is not a producer but a tollgate: he stands on a spot the community has made valuable and charges the community for the use of it. And because land underlies everything — every farm, every factory, every home must stand somewhere — the toll is universal and inescapable. This, and not any defect of industry or thrift or character, was for George the root of the poverty that shadowed progress: that the value the many created was captured by the few who held the ground. He was emphatic that the fruits of a man's own labour were sacredly his — he was no socialist, and said so often and hotly — but the bounty of nature, and the increment the community laid upon it, belonged by right to all.⁵

To Ricardo's mechanism George added one of his own, and it was prophetic. The expectation of rising land values, he saw, sets off a speculation that makes the whole process worse. If land will be worth more next year, its owners have reason to hold it now — to keep it idle or half-used, waiting for the price to climb. But land held out of use is land the community must do without; to meet its needs, production is forced onto land further out, or driven harder where it sits, and the margin is pushed past where present need alone would set it. Speculation, in other words, lifts rent above even the level the bare growth would justify, and depresses wages further, by withholding the good land and crowding everyone onto the poorer.

And because the expectation feeds on itself, the speculation inflates until it cannot be sustained, and breaks. George argued that the great commercial depressions of his century were, at root, land crises — booms in the value of the ground, overrunning what any use could justify, collapsing and dragging the productive economy down behind them. He was describing, a century and a half early and in all its essentials, the mechanism of the land and housing bubbles that would convulse the next century and our own; that the cause of the boom and the cause of the bust were the same ownership of the same scarce thing.⁶

What, then, was to be done? George's answer was as bold as his diagnosis, and far more carefully built than his enemies allowed. He did not propose to seize the land. He had no wish to nationalise farms or dispossess households or set the state to managing fields — he saw, as clearly as any critic, that private possession gives land its best use, and that the security of improvements must be preserved or no one would improve. What he proposed was to leave the land in private hands and take its rent. A tax upon the value of land — the bare site, excluding every improvement — pitched high enough to absorb very nearly the whole of the rent, and used to fund the government in place of all other taxes. The single tax.⁷

The proposal carried three virtues at once, and the combination is what made it so beguiling. It was just: it returned to the community the value the community had created, and left to each person the full fruits of his own labour, taxing nothing that anyone had made. It was sufficient: the rent of land, George believed, was a fund so vast that it could meet the entire expense of the state, allowing every other tax — on wages, on trade, on industry, on the products of effort — to be swept away. And it was efficient in a way no other tax could match: because land is fixed in quantity, a tax on its value cannot shrink the supply or drive it into hiding, as a tax on labour or capital or goods will; it falls on a surplus, alters no one's conduct at the margin, and so carries none of the deadweight loss that every other tax inflicts. A levy that was just, ample, and costless — and that would, into the bargain, end the speculation by stripping away the gain from holding land idle. It is no wonder the idea swept the world. The deepest of its claims, the efficiency one, is not a Georgist enthusiasm but a theorem of public finance; the ninth plate will prove it, and weigh how much of the rest can be made to stand.⁸

The argument is more than a historical curiosity, and parts of it are simply correct. That the value of land is largely a social creation is true, and important, and too often forgotten. That a tax on pure land rent is uniquely efficient — that it can raise revenue without the distortion every other tax carries — is not a Georgist enthusiasm but a theorem, which the ninth plate will prove, and which remains one of the most underused results in public finance. And that land, and the housing built upon it, sits closer to the centre of wealth and inequality than the textbooks of the twentieth century allowed is a thesis the twenty-first century's data have powerfully revived, as the tenth and twelfth plates will show. On its central insight — that rent is unearned, that taxing it is efficient, that land is the quiet engine of maldistribution — George was largely right.⁹

But the indictment overreaches at its edges, and honesty requires marking where. The boldest claim — that land rent alone could fund the entire state, the single in the single tax — was probably never quite true and is not true now; pure land rent, though large, is not by itself enough to run a modern government, and the totalising form of the proposal asks more of the land than the land can bear. The transition is a graver difficulty still. A man who has bought his land at a price already reflecting its rent — often with the savings of a lifetime, or a mortgage he is still paying down — has not pocketed the unearned increment; the seller did. A tax confiscating the rent at a stroke would fall not on the windfall-takers but on him, wiping out a value he paid for in full. A justice aimed at the unearned can, applied suddenly, land hardest on the innocent. And the old practical trouble has never gone away: to tax the value of bare land one must first separate it from the value of the buildings and drains and clearing heaped upon it, and that assessment, though far from impossible, is delicate enough to have halted many a reform at the threshold. These are not refutations. They are the boundaries of a true idea — and the plates ahead return to each.¹⁰

For a moment George was everywhere. Progress and Poverty sold in the millions, was translated across Europe and Asia, pressed on workingmen and read aloud in lecture halls, and by some reckonings was outsold in English, in the 1890s, by no book but the Bible; its admirers ran from Shaw, who credited it with making him a socialist, to Einstein, who called it a marriage of intellectual keenness and the love of justice. Its author, the self-taught printer, ran for mayor of New York in 1886 and came second — ahead of the young Theodore Roosevelt, behind a Tammany-backed Hewitt, amid lasting and credible charges that the count was rigged against him. Even the board game now sold as a monument to acquisitive capitalism began life as a Georgist parable, patented by a follower to show how the landlord's rent grinds the other players, one by one, into ruin.¹¹ A movement took his name; single-tax clubs sprang up on three continents; and the idea seeped, in diluted forms, into the law of many places — the land taxes of Australia and Denmark, the split-rate levies of Pennsylvania towns, the public land-leasing of Hong Kong and Singapore, the rating of unimproved value across the Anglophone world — and into the mainstream of politics, in Churchill's famous orations against the unearned increment.¹²

The single tax, in its pure and total form, was adopted nowhere, and for the reasons the last movement gave. But that is the wrong measure of George. His enduring bequest is not the programme but the insight beneath it: that there exists a kind of income — the rent of scarce, unmade things — that is at once unearned and, uniquely, taxable without harm, so that here, if nowhere else, justice and efficiency point the same way. That insight did not die with the single-tax clubs. It is the hinge of this volume's middle, the key the ninth plate will turn, and the lens through which its last plates read an economy in which the rent of land — and of much that has come to behave like land — quietly dominates. Ricardo found the mechanism; George found the question and the remedy; and though the remedy overreached, the question he forced — by what right is the increment of the many kept by the few? — has never been answered, only postponed. The plates that follow take up the postponement.¹³
