The Serrata

Before it froze, Venice had invented a machine for making poor men rich.

The device was a contract called the colleganza, and it worked like this. A wealthy Venetian who did not want to spend eighteen months at sea would put up the capital for a trading voyage. A young man with no capital at all would put up himself: he would take the ship, sail to Constantinople or Alexandria, do the buying and selling, survive whatever the Mediterranean had in mind, and come home. The profits were divided, typically with the traveler taking a quarter for having done the dangerous part.

Consider what this instrument accomplishes. It converts courage into equity. A man with nothing but nerve and competence could take one voyage, come home with a share, put that share into the next voyage as capital, and within a few cycles be financing other young men. There was a documented route from nobody to somebody, and it ran through a legal form that any notary in the city could write.

The result was one of the most socially fluid commercial societies in medieval Europe. New names kept appearing in the Venetian records. New families kept turning up in the Great Council, the body that governed the Republic. Historians who have studied the surname data can watch it happen: a merchant class that kept getting refreshed from below, because the mechanism for refreshing it was sitting in every notary’s office.

Venice became, on the back of this, the richest and most sophisticated commercial power in Europe. It had double entry bookkeeping, marine insurance, transferable government debt, and a shipyard that could assemble a galley in a day. Nothing in Europe was close.

1297

Then the families who had arrived stopped the door behind them.

In 1297 the Great Council was closed. The formal mechanism was procedural, as these things usually are: membership was restricted to men whose families had already sat on the Council, which converted a political body into a hereditary one without ever using the word. Within a few decades the arrangement was formalized further, with an official register of the families entitled to participate. The Venetians called it the Golden Book.

The closing has a name. La Serrata. The lock in.

And then, in the decades that followed, the Republic did something that looks almost too neat to be true, except that the records show it plainly. Having sealed the political door, it went after the economic one. The new hereditary nobility used its exclusive hold on the Great Council to erect barriers around the most lucrative parts of long distance trade, and the colleganza, the instrument that had carried them up, fell away beneath them. The route was closed by the people who had just finished climbing it.

Economists have studied this episode closely. Diego Puga and Daniel Trefler reconstructed it from a database of 8,178 parliamentarians and their families’ use of the colleganza in the periods immediately before and after 1297, and the sequence they document is the important part. The mobility came first. The new families rose through it. Then the new families, now established, closed the political system, and then closed the economic mechanism that had made the political system worth entering.

It was not stupidity. From inside, every step was rational. If you have arrived, the arrival of others dilutes you. Each individual closure was in the interest of the people voting on it, and the people voting on it were, by then, the only people entitled to vote.

What happened next, which is nothing

Here is the part that matters for this book.

Venice did not collapse. There was no catastrophe, no sacking, no sudden ruin. That is what makes it the right historical model rather than the usual apocalyptic ones.

The Republic lasted another five hundred years. It stayed wealthy. It stayed beautiful. It kept its art, and acquired more of it. Its aristocracy remained cultured and its palaces remained magnificent and its citizens, by the standards of Europe at the time, remained comfortable.

It simply stopped mattering.

Its share of Mediterranean trade declined. When the Atlantic routes opened and the center of European commerce moved west, Venice did not adapt, because the families positioned to adapt were the families whose position depended on the existing arrangement. The financial innovation stopped. The shipyard that had astonished Europe became a place where they did things the way they had always done them.

By the eighteenth century, the most commercially inventive society in medieval Europe was known primarily for carnival, gambling and tourism. It had become a place people visited to see what used to be there. When Napoleon ended the Republic in 1797 he encountered essentially no resistance, because there was nothing left with an interest in resisting.

Five centuries of pleasant, wealthy, decorated stasis. Nobody suffered dramatically. Nothing further happened.

It is not only Venice

I lean on Venice because the sequence is unusually well documented, but the pattern is not rare, and a second case is worth putting alongside it because it shows the same thing happening at a completely different scale.

Between 1405 and 1433, Ming China sent seven enormous fleets into the Indian Ocean under the admiral Zheng He. Some comprised more than three hundred ships and tens of thousands of men, and they reached Ceylon, Hormuz and the Swahili coast of East Africa. Nothing in Europe was remotely comparable. The capability was real, it was state of the art, and it was decisively ahead of anyone else on the planet.

Then the court decided to stop. The voyages ended after 1433, the faction that had backed them lost, and the money went to the northern frontier where nomadic powers were pressing. The point is not that the decision was irrational. The costs were enormous and the northern threat was real.

The point is what happened next. The capability was not mothballed. Chinese pre-eminence in shipbuilding, navigation and seamanship withered within a few decades. When the Portuguese entered those same waters about fifty years later, they did not encounter a competitor that had chosen to stay home. They encountered an absence.

That is the property of stasis that makes it dangerous rather than merely disappointing. A society that stops does not retain the option to resume. Skills live in people who are practising them, and the institutions that trained those people dissolve within a generation of losing their purpose. Venice kept its Arsenal, the shipyard that had astonished Europe, and it kept building ships in it for centuries. It could not have rebuilt the Arsenal from scratch, and it never again built anything like it.

The frozen world does not preserve its own ability to unfreeze. That is the specific thing being lost, and it is why the mechanisms in the next chapter have to be installed before the freezing rather than after it.

The same five locks

Now map the Serrata onto the five jobs, because Venice closed by political decision what this book argues will close by demographic drift, and the resulting structure is the same.

The price of time. A society with a near zero discount rate does not stop investing. It invests in permanence. It maintains, preserves, restores and insures, because those activities have certain returns over long horizons, while genuinely new ventures have uncertain ones. Venice kept its palaces in perfect repair for four hundred years. It did not build a new kind of city.

Capital. The Golden Book families held their positions until the Republic ended. Wealth in a frozen system does not need to be defended aggressively, because there is no mechanism by which it could be lost. It simply sits, compounding, held by the same names across centuries.

Ideas. The intellectual and commercial techniques that made Venice extraordinary were substantially invented in the two centuries before the closing, and substantially not improved in the five after. When the people who benefit from the current way of doing things are also the people who decide what gets tried, the current way of doing things is what gets tried.

Risk. This is the clearest parallel and the most instructive. The colleganza was a risk contract. Its entire function was to let someone with nothing wager their life against someone else’s capital. Ban it and you have not merely closed a route to wealth. You have removed the only mechanism by which the society converted danger into position. Venice stopped sending its ambitious young men into the eastern Mediterranean and started keeping them at home, safe, and idle.

Vacancy. The Council seats were hereditary. There were no openings, because there were no exits, because the qualification for entry was having already been in.

Five locks, all turned, and a wealthy society that lasted half a millennium without doing anything.

The pleasant version

I want to resist catastrophism here, because I think it is both dishonest and strategically foolish, and because a frozen world is genuinely not a horror.

Let me put the good side of it as strongly as I can.

Nobody dies. Take a moment with that, because everything else in this chapter is a second order consideration next to it. The single greatest source of human suffering across all of history is that people we love stop existing, and in this world that stops happening. Every argument I have made about turnover is an argument about the cost of a world in which grief becomes rare, and any accounting that does not put that in the first column is not an accounting.

It is safe. Accident rates fall for decades, because a society of very long lived people will pour resources into safety with an intensity we can barely imagine. Diseases are cured, because there is time and money and enormous motivation.

It is rich. Compounding at two hundred years does astonishing things to aggregate wealth, and even a badly distributed enormous pile is a large pile.

It is patient. This is real and it is the strongest single argument against my whole thesis. A society with a near zero discount rate will finally do the things we have never been able to justify: seawalls with two hundred year payback periods, forests planted for their maturity, infrastructure built to last, restoration projects measured in centuries. Climate policy becomes straightforward, because the people voting on it will be the people living with the outcome. That is not a small consolation. It might be worth quite a lot of stasis.

And it is beautiful, probably. Frozen societies tend to be. When capital cannot be productively deployed into new ventures it goes into craft, ornament, preservation and display. Venice is gorgeous. That is not incidental to what happened to it.

If you are inside it and comfortable, this is not a dystopia. It is the nicest place anyone has ever lived.

The thing that is missing

What is missing is the possibility of anything else.

Not a specific good thing. The category. The frozen world does not lack innovation in the way a poor country lacks innovation, which is a shortage that money and talent could fix. It lacks the mechanism by which the arrangement of things could come to be different from how it currently is. Nobody can enter, nobody can be displaced, nothing can be reallocated except by the consent of those who currently hold it, and they have no reason to consent.

The word for this is not decline. Venice did not decline for a very long time, and by many measures it never did. The word is closure.

And a closed society has a peculiar property when you look at it through the finance lens this book has been using. Recall the idea of terminal value, the part of an asset’s worth that lies beyond the period anybody bothered to forecast. In an ordinary valuation, that residual is most of the number. The great majority of what any long lived enterprise is worth comes from the years nobody modeled, because those years might contain anything.

In a closed system, that is no longer true. The far future is not uncertain, and it is not full of possibility. It is the present, extended. You can forecast it perfectly, and the forecast is: this, again.

A civilization in that condition has no terminal value. Not because it is about to end. Because nothing beyond the horizon differs from what is inside it, and value beyond the horizon was only ever a way of pricing the chance that things could turn out otherwise.

That is the world we are drifting toward, and the drift is not being driven by anything malicious or even by anything anyone has decided. It is being driven by five separate mechanical consequences of people not dying, none of which has a replacement, none of which is anybody’s responsibility, and all of which are already faintly visible in the data.

The remaining question is whether the replacements can be built, and by whom, and in time.
