With this volume the work comes to the last of the five fundamental prices, and to the strangest. The wage was the price of labour, the rent the price of a position, the rate the price of time, the premium the price of risk; each was, however contested, the price of something — of an effort, a place, a delay, a danger. This volume concerns a price that is the price of nothing of the kind: the price of standing between two other prices, the cut kept by the one who places himself between a buyer and a seller and takes a slice of the difference. It is the broker's commission, the dealer's spread, the merchant's markup, the platform's take — the wage, or the toll, of the middleman. And it opens with the oldest suspicion in all of commerce, a suspicion older than economics and nearly as old as trade itself: that the middleman is a parasite. He grows no grain, the charge runs, and weaves no cloth, and forges no tool; he adds nothing to the goods that pass through his hands; he merely inserts himself between those who make and those who use, buys cheap from the one and sells dear to the other, and pockets a difference he has done nothing to earn. The charge is intuitive, ancient, and — as this plate will argue — both seriously mistaken and not entirely wrong. For the suspicion conceals a function, a real and often indispensable service that the producer and consumer could not perform for themselves; and yet it also fastens, however crudely, on a real danger: that the one who stands between can sometimes charge not for any service but merely for being impossible to get around. The whole of this volume lives in the space between those two truths, and its question is the one the masthead would predict: when does the middleman earn his cut, and when does he merely levy it?
The suspicion is worth taking seriously, for its pedigree is long and its grip is strong. Aristotle drew a line between the natural acquisition of what a household needs and the unnatural art of moneymaking, and placed the retail trader and the moneylender firmly on the wrong side of it, as men who made money breed from money rather than from any honest making. The medieval Church inherited and sharpened the suspicion: it condemned the forestaller who bought up goods before they reached the market, the regrator who bought to sell again unchanged at a higher price, the engrosser who cornered a commodity — all of them middlemen, all suspected of profiting from a scarcity they manufactured or a passage they obstructed rather than any value they added. And the suspicion has never died. It surfaces in every generation's hatred of the speculator, the profiteer, the scalper, the moneylender; it has, again and again, fastened with peculiar venom on the trading minorities who so often filled the middleman's role — the merchant cast as a parasite upon the honest producer, and the parasite cast, too often and too cruelly, as an alien. Beneath all these forms lies a single intuition, and it is not a foolish one: that the man who makes a thing, or grows it, or carries it on his own back, has plainly earned his bread, while the man who merely arranges for it to pass from one hand to another, and skims as it passes, has done something far harder to see as honest work.
And yet the intuition rests on a failure to see what the middleman actually does, which is to bridge the gaps that keep a buyer and a seller apart — gaps that are real, that are costly, and that do not close themselves. There is the gap of space: the grain is grown where land is cheap and plentiful and is wanted where people are crowded and fields are few, and someone must carry it from the one place to the other. There is the gap of time: the harvest comes in once a year and is eaten all year round, and someone must hold it through the months between. There is the gap of search: the man who has a thing to sell and the man who wants it may never find each other in a world of millions, and someone must bring them together. There is the gap of knowledge: what is available, what is sound, what is a fair price, are things that must be known, and someone must know them. There is the gap of risk: the thing held against a future sale may spoil or fall in value, and someone must bear that hazard. And there is the gap of trust: the stranger's goods may be shoddy and his promises empty, and someone must stand behind them. Every one of these gaps is a real obstacle to the trade that both sides want, and the closing of each is a real service. The middleman is the one who closes them, and his cut is the price of the closing.
He grows no grain, it is true; but grain in the granary in winter is worth more than grain in the field at harvest, and the keeping and the carrying of it there is as real a making as the growing.
Seen so, the parasite charge rests on an illusion — the illusion of the direct transaction that the middleman is imagined to have interrupted. The producer who grumbles that he could have sold for more, and the consumer who grumbles that she could have bought for less, are each picturing a trade between them at some middle price, with the middleman's cut simply removed and handed to one or the other. But that trade, in the great majority of cases, does not exist to be had. Without the merchant, the grain does not travel from the surplus province to the hungry city at all, or travels so seldom and so dearly that the city goes without; without the dealer, the man who must sell today cannot find the man who wishes to buy today, and either waits indefinitely or sells for whatever the moment yields; without the one who bears the risk and vouches for the quality, the trade is too dangerous to strike and is not struck. The middleman's cut is not subtracted from a transaction that would otherwise have happened at a better price; it is the price of a transaction that would otherwise not have happened, or have happened worse. And the proof is in the willingness of both sides to deal with him: the producer sells to him because it beats the alternative of not selling, the consumer buys from him because it beats the alternative of not buying, and the cut he keeps is, in the ordinary case, less than the value he has created by making the trade possible at all. Both sides are better off with him than without — which is the signature of a service genuinely rendered.
But the suspicion, though wrong as a blanket charge, is not pure superstition, and an honest reckoning must grant what is true in it. For the middleman's position — standing between, in the gap through which both sides must pass — is not only a place of service; it is a place of power. The same position that lets him serve lets him levy. If he is one dealer among many, competition will hold his cut down toward the true cost of the service he provides, and the parasite charge fails entirely. But if he is the only road between the producer and the market — the sole bridge, the controlling platform, the gatekeeper who cannot be bypassed — then his cut need bear no relation to any service at all. He can charge, simply, for being unavoidable; can widen his spread not because the bridging has grown costlier but because those who must cross have nowhere else to go. This is the middleman not as servant but as toll-keeper, and his cut is then exactly what the ancient suspicion named it: a levy extracted from a transaction he obstructs rather than enables, a toll upon passage. The volume will meet this figure in his own right, later, under his proper name; here it is enough to see that he is real, that he is the kernel of truth inside the old slander, and that he wears, from the outside, the very same garment as the honest servant — for both, in the end, simply take a cut of the difference between two prices.
The same position that lets the middleman serve lets him levy; and from the outside the wage of his service and the toll of his power are charged in the very same coin.
Here is the difficulty that will occupy the whole volume, and it is a deep one. The wage of a service and the toll of a position are not merely similar; they are, in the cut itself, indistinguishable. Both appear as a spread, a markup, a commission — a slice of the gap between what the seller receives and what the buyer pays. Nothing in the size of the cut alone reveals which it is, for a large cut may be the fair price of an arduous and valuable service, and a small one the lazy toll of an easy monopoly. Worse, the two are very often mixed in the same hand: the same merchant who genuinely carries the grain and bears the risk may also, where his position allows, charge somewhat more than the carrying and the bearing are worth, so that his cut is part wage and part toll in a proportion no invoice discloses. And the two parties to the transaction cannot be trusted to sort it out, for each is biased to his interest: the customer, who feels the cut as a deduction from his due, is inclined to call the whole of it a toll and the middleman a parasite; the middleman, who feels the cut as the reward of his trouble, is inclined to call the whole of it a wage and himself a benefactor. The truth lies somewhere between their two accounts, and never exactly where either places it — which is why the line between the earning and the levying is so endlessly disputed, and so rarely drawn with any honesty by those with a stake in where it falls.
The task of this volume is to draw that line as honestly as it can. It begins from the verdict this plate has reached: that the oldest suspicion is, as a general charge, mistaken — the middleman is no parasite but the closer of real gaps, and his cut is, in the competitive ordinary case, the earned wage of a service as genuine as any producer's — but that the suspicion is not empty, for it points at the real and recurring figure of the toll-keeper, the middleman whose position lets him charge for more than he does. Between the honest servant and the bare toll-keeper lies every actual intermediary, mixed of both in proportions that shift with the competition he faces and the indispensability he commands; and the volume's work is to take the chief forms of standing-between, one by one, and ask of each how much is service and how much is toll. It will ask why buyers and sellers fail to find each other, and what the finder earns; it will ask what the dealer's two prices conceal, and what the holding of inventory truly costs; it will ask what immediacy is worth, and what must be paid against the hidden knowledge of an informed counterparty; it will ask what the bank earns by standing between the saver and the borrower, and what the arbitrageur earns by pressing two prices into one; and it will ask, at the last, what the platform takes, and where the servant ends and the toll-keeper begins.
For the cut kept by the one who stands between is, like every price in this table, a verdict on a hidden contest — here the contest between the service a middleman renders and the toll his position lets him exact — and it is, like every price, commonly mistaken for a simple fact of nature: the customer sure it is all extortion, the middleman sure it is all desert, and the truth, as ever, harder won than either. The volume that follows will try to win it, form by form, until it can say of the broker's commission and the dealer's spread and the banker's margin and the platform's take how much is the honest price of standing usefully between, and how much the bare toll of standing unavoidably between. With that, the last of the five prices will have been anatomized, and the first of the table's six families — the fundamental prices, the wage and the rent and the rate and the premium and the spread — will stand complete. As the table says of every price, first to last: the argument remains open.
