As AI agents and robots begin to do the work of clerks, managers and labourers, the comparison with Rome suggests itself: a citizenry displaced by owned intelligences and kept quiet with bread and games. Hayekian Markets, Simulacrum, examines the parallel through the knowledge problem and the price system. Roman slaves ran businesses through the peculium, the grain list became an instrument of patronage, and the poor found their patrons among generals. The essay asks what happens to an economy when much of its population can no longer bid, whether a universal floor can be paid for and on what terms it could be squared with liberty, and why falling prices and open entry may matter more than any transfer. It is written in a patient, systematic manner, with Roman law and monetary theory as its instruments.

A man who sets out to describe the economy of a world that does not yet exist should begin by admitting how little he can know about it. That is not modesty. It is the method. The price of a loaf in a year when robots build robots, the number of people whose work will still be bought, the things they will be paid to do: none of these is known now. Nobody can collect them, because they have not yet happened. They will be discovered, if they are discovered at all, by millions of people trying things and watching what others will pay. Anyone who tells you the answer today, whether in the form of a forecast of mass unemployment or a promise that new jobs will appear as they always have, is claiming knowledge that does not exist.
All the same, one is not reduced to silence. We cannot know the outcome, but we can reason about the structure: about what kind of order we are in, what it needs in order to keep working, and what kinds of remedy would quietly destroy it. The comparison with Rome, which has been put to me, is a good place to start, though not quite for the reason usually given.
The usual picture is simple. The Roman citizen-farmer came home from the legions to find that the great estates, worked by slaves taken in war, could undersell him. He sold his plot, drifted to the city, and lived on the grain dole and the games. The slave was a machine for labour, and the citizen could not compete with a machine that needed only to be fed.
There is truth in it. But the picture leaves out what made the Roman slave economically formidable, and it is exactly the part that matters now. The slave was not only a pair of hands. He was very often the mind of the business. Roman law developed the peculium, a fund of property that the master left in the slave's control. Legally it was the master's; in practice the slave traded with it, borrowed against it and ran shops, workshops and ships on its strength. The praetor gave third parties an action, the actio institoria, against the master who had set a slave or anyone else in charge of a business, so that people could deal with the manager as if they were dealing with the owner. A great deal of Roman commerce was carried on in this way. The master stayed at a distance while the slave kept the accounts, knew the suppliers, judged the customers and saw when a cargo was worth buying.
There was a further twist. In 218 BC the lex Claudia, proposed by a tribune and carried, Livy says, against the bitter opposition of the senate, forbade senators and their sons to own seagoing ships carrying more than three hundred amphorae: enough to ship the produce of their own estates, not enough to trade on a large scale. Commerce was held to be beneath the senatorial order. Such a rule does not stop the rich from trading. It only makes them trade through intermediaries, and the readiest intermediary was the owned intelligence with a peculium.
So the Roman parallel is sharper than it first looks. The citizen was not displaced by brute labour alone. He was displaced by owned practical knowledge: by agents who knew the particular circumstances of time and place, worked on behalf of a principal, and could be multiplied by purchase. That is a fair description of what is now being built.
Before asking what to do with the people who cannot compete, we should ask what the machines are actually substituting for, because the answer decides almost everything else.
The knowledge an economy runs on comes in roughly three kinds. There is scientific knowledge, explicit and codifiable, the kind that can be written in a textbook and is in principle available to a central authority. There is the knowledge of particular circumstances: that this warehouse has spare space this week, that this customer will pay on time, that this seam of ore is thinner than the survey said. And there is tacit knowledge, skill that its possessor cannot fully put into words. The planners of the last century failed because they imagined the first kind was all there was. They gathered statistics and gave orders, and the shortages followed, because the knowledge that actually coordinates production was scattered among millions of people and could not be gathered in.
What is new about the present machines is that they reach into the second kind, and perhaps the third. An agent placed in a firm, reading its correspondence and watching its operations, accumulates something very like the merchant's knowledge of time and place. This is precisely the function the Roman institor performed. It is a serious development and I do not want to minimise it.
But there is a fourth thing, which no machine supplies and which the comparison with Rome tends to hide. An economy exists to serve ends: the wants of the people in it. Those ends are the most dispersed knowledge of all. They are not facts lying about waiting to be measured. They are formed and revised each day, in each household, as people weigh one thing against another. The price system does not just carry information about what is scarce. It carries information about what is wanted, and it carries it only from those who have something to offer in exchange. A want that cannot be backed by a bid does not appear in the signal. As far as the price system is concerned, it does not exist.
This is where I think the usual discussion goes wrong. It treats the income of displaced workers as a problem of charity, or of keeping order: how do we feed and pacify the people who are no longer needed? The prior problem is one of information. If a large part of the population loses the means to bid, their wants drop out of the system that decides what is produced. The machines will go on producing, very efficiently, for whoever still holds purchasing power. Production will then be steered by a narrowing set of signals. The economy will not have been planned. It will simply be listening to fewer people.
Rome had exactly this problem, and its answer is instructive.
When the plebs of the city ceased to be an economic force, they did not cease to want things. They lost the market channel through which wants are normally expressed, and other channels opened. One was the riot. Another was the crowd in the theatre and the circus, where the acclamations and the jeering of the people were heard by the magistrate who paid for the games and, later, by the emperor in his box. Juvenal's sneer that the people who once handed out commands, fasces and legions now longed anxiously for only two things, bread and the races, is usually read as contempt for the mob. It can be read another way. The circus was where an excluded population still sent a signal. It was a very crude price system, with one buyer and a hundred thousand sellers of applause.
The grain dole was the other half of the arrangement, and it shows what becomes of a transfer once it turns into an instrument of rule. Gaius Gracchus established subsidised grain in 123 BC. Clodius made it free in 58 BC, and by then about 320,000 men were on the list. Caesar cut the list to about 150,000; under Augustus it settled near 200,000. Every one of these changes was a political act. The list of recipients was a list of clients, and whoever controlled it controlled a considerable part of the city. The cura annonae, the care of the grain supply, became one of the great offices of state, and in time a prefecture answerable to the emperor alone. The dole was not a floor beneath a free society. It was a lever in the hands of whoever could pull it.
The third outlet was the army, and here the consequence was gravest. In 107 BC Marius, needing men for the war against Jugurtha, enlisted volunteers from the capite censi, citizens too poor to be counted in the census classes. Scholars argue about how far this was a lasting reform. What is not disputed is the direction of the following decades: soldiers who looked to their general rather than to the Republic for land and pay. Within twenty years Sulla marched his legions on Rome. The men whom the economy no longer needed had found a patron who did need them, and he was not the Senate.
Bread, games and the legions are three versions of one thing. When people cannot take part in the impersonal order of exchange, they are drawn into personal orders of dependence, and the man at the top of a personal order is not restrained by rules. This is the road to serfdom in its Roman form. No one intended it. It followed from the structure.
Now to the question as it was put: if the machines bring down the cost of goods, will a universal income be affordable, and is it affordable in the present economic model?
I agree with the doubt about the present model, though perhaps for a different reason. The trouble is not that output will be too small. If robots build robots at roughly the cost of energy and materials, output may well be very large. The trouble is that our states draw their revenue overwhelmingly from wages and from spending financed by wages. A floor paid for by taxing labour, in a world where labour's share of income is falling, is a bridge whose supports are being removed while traffic is put on it. On that model, the answer is no.
But the question "is it affordable?" is being asked in today's prices, and today's prices are exactly what will not hold. Here the pretence of knowledge cuts both ways. Those who say a universal income is impossible are pricing it in a world where a meal, a coat and a doctor's consultation cost what they cost now. Those who say it will be easy are assuming they know the price structure that will emerge. Neither knows. What can be said is something about the shape of that structure.
Where the machines can make something, its price will tend to fall toward the cost of the inputs the machines cannot make more of. Those inputs are energy, land and position, certain materials, and the narrow channels that legal privilege may create around the machines themselves. Prices will not fall evenly. They will fall steeply for whatever can be reproduced and hardly at all for whatever cannot. A floor that buys abundant food and clothing may still not buy a room in a city. The question of affordability then becomes a question of who holds the scarce factors and how those holdings are taxed, and that is a much older question than artificial intelligence.
There is a second route by which the dividend of the machines can reach people, and it is one our monetary arrangements are built to block. If productivity rises sharply and the stream of money is kept steady, prices fall, and everyone who holds money or earns a fixed sum grows richer without any transfer at all. Falling prices of this kind, caused by abundance and not by a collapse of credit, are no disease. They are the ordinary way in which the gains of invention spread through a society. But the central banks have spent a generation teaching the public that falling prices are a catastrophe to be prevented by creating money. If they meet the abundance of the machines with fresh money, so as to hold the price level up, they will take back the gain that falling prices would have handed to everyone. A great deal of the debate about whether we can afford to pay people may turn out to be a debate about whether we will let them keep the cheapness they have earned. It is one more reason to doubt that money should be a monopoly at all.
I have no objection in principle to a floor. In a society of strangers, where nobody can call on the clan or the village into which he was born, it is a legitimate protection against a risk common to all. Hayek wrote in so many words that the assurance of a certain minimum income for everyone, "a sort of floor below which nobody need fall even when he is unable to provide for himself", was a necessary part of the Great Society. Commentators argue about how widely he meant it. The principle is clear enough: a floor is compatible with a free order. What a free order cannot survive is a floor administered like the Roman list.
So the question is never only whether, but how, and Rome supplies the negative test. A floor that is compatible with liberty must be:
None of this guarantees that a floor will be affordable. It guarantees only that, if we do have one, it will not turn into the grain prefecture.
Rome, it should be remembered, kept certain domains from its slaves. A slave could manage a bank and run a ship, but he could not vote, hold office, plead as a citizen, or serve in the legions. It is tempting to answer with a modern list: these occupations shall be reserved to human beings. I think that would be a mistake. Nobody can know which tasks machines will do badly, and a list of protected trades is a guild privilege under another name. The guilds protected their members for a while and impoverished everyone else for much longer.
But there is a domain that must be reserved, and it is not a set of jobs. It is the making and judging of the rules. A spontaneous order lives on general rules that nobody designed as a whole: property, contract, tort, the habits of honest dealing. They grew up among people who had to live under them and correct them case by case. If the judging of disputes and the drafting of rules pass to systems owned by a few principals, the rules will gradually come to serve the principals, whatever their intentions, because those who own the judges will be the only parties whose interests the judges are built to understand. Rome kept the courts and the assemblies for citizens. It was right about that much, even if it was wrong about almost everything else concerning who counted as a person.
And there was one thing the Roman slave could never fully do, however able: own in his own right. The peculium was revocable at the master's will. Everything the slave built belonged, finally, to someone else. This seems to me the real centre of the comparison, and the place where we may yet do differently. The danger is not that intelligences will be owned. The danger is that they will be owned by few.
Picture two versions of the coming world.
In the first, the agents and robots are held by a small number of great houses, as the familiae of slaves were held by the senatorial and equestrian families. They hold them because the cost of entry has been raised: licences to operate models above a certain size, approval regimes that only incumbents can afford, rules on data and energy written with the incumbents' lawyers in the room. Everyone else is a citizen without an occupation, voting for whoever promises a larger dole. This is Rome, with better plumbing.
In the second, the machines are cheap, various and widely held. A carpenter has three agents running his quotations, his ordering and his accounts. A village cooperative owns its own fleet of field robots. A retired nurse runs a small advisory practice through a dozen owned assistants, and earns from them as a Roman householder earned from the slave who kept his shop. In this world the displaced worker is not merely a recipient. He is a dominus in miniature, and his wants enter the price system because he has something to sell: the output of the intelligences he owns.
Nobody can design the second world. Any scheme to hand out machine ownership by decree would need exactly the knowledge that does not exist: which machines, for whom, doing what. What can be done is negative and general. Keep entry open. Refuse the licensing moats that incumbents will request in the name of safety. Treat the concentration of compute and energy under special privilege with the suspicion we owe any monopoly that owes its position to the state. Let the price of a capable agent fall as far and as fast as competition will drive it. Competition is a procedure for discovering what nobody yet knows, and among the things nobody yet knows is what ordinary people will do once each of them commands a household of tireless clerks.
The Romans did not lose their Republic because they had slaves. They lost it because the slaves belonged to too few, the excluded found their patrons among generals, and the bread was distributed from a list. We are building owned intelligences on a scale Rome never imagined. Whether they belong to many or to few will settle more than any income scheme, and that question is being decided now in the rules on who is permitted to build and run them.
