Zero-sum

Not many people walk around saying "the world is zero-sum" or "the world is not zero-sum." But a surprising number of today's loudest arguments rest on one of those two premises without ever naming it.

When someone says inequality doesn't matter because the economy is growing—that's a claim the world is not zero-sum. When someone says billionaires are the reason wages are stagnant—that's a claim it is. When politicians argue about tax policy, trade, immigration, tech regulation, the unstated load-bearing assumption underneath is almost always: is there a fixed pie or isn't there?

It's easy to engage with the surface-level consequences—the housing debate, the wealth tax debate, the "learn to code" debate—without noticing they all trace back to the same disagreement about whether one person's gain requires another person's loss.

I think both sides of that disagreement are right, and both are wrong, and the interesting part is figuring out where the boundary sits—because that boundary is where most of today's social friction actually lives.

Money is zero-sum. That's not an opinion.

Start with something that should be uncontroversial but somehow still is: barring money printing, the supply of money is finite. If you control a larger fraction of it, someone else controls a smaller fraction. That's arithmetic.

Rather than thinking in dollar terms, think in percentages of the money supply. What can 0.0001% of the supply buy you? That framing makes two things immediately obvious:

The money game is literally zero-sum. A larger slice for you means a smaller slice for someone else.
What a given slice can buy has changed dramatically. 0.0001% of the money supply today buys you things that didn't exist 200 years ago—and would have been magic 50 years ago.

Both of these things are true at the same time, and most of the zero-sum debate amounts to people emphasizing one while ignoring the other.

What the entrepreneurs miss

The standard entrepreneurial line goes something like: "Stop thinking zero-sum. The pie is growing. We're creating value, not redistributing it."

This is true but shallow.

Money is a proxy for things beyond purchasing power. It's a proxy for influence, for political access, for optionality, for the ability to shape the rules everyone else plays by. When wealth concentrates structurally—not because a few people got lucky, but because the system reliably funnels it in one direction—that's a problem even if the absolute standard of living is rising.

Telling someone "your slice is smaller but it buys more stuff" doesn't address the fact that their relative power is shrinking. And relative power matters, because power determines who sets the rules of the next round.

What the other side misses

The populist response is usually some version of: "The game is rigged. Redistribute."

This is also true but shallow.

Yes, the game has structural unfairness. But the proposed fix—take from the haves, give to the have-nots—is symptom treatment. It addresses the output of the system without changing the mechanism that produces the imbalance in the first place.

The uncomfortable part is that the structural advantage right now isn't inherited wealth or political connections in the traditional sense. It's the ability to use technology—software, AI, automation—productively. There is a large and growing fraction of the population that consumes software but doesn't produce with it. And because the economy's center of gravity keeps shifting toward software-mediated work, that gap compounds.

Redistribution doesn't fix this. It just resets the scoreboard temporarily while leaving the underlying game unchanged.

The greenfield illusion

Entrepreneurs have another move: "Go build something new. Compete in expanding markets. That's where the non-zero-sum action is."

There's real truth here. If you're operating in a market that's growing—one that barely existed last year—it doesn't feel zero-sum. You're not visibly taking someone else's customers. You're creating a new category.

But money can only be spent once. If someone spends money on your new thing, they're not spending it on something else. It's entirely possible that Netflix out-competes groceries for a given household's budget, or vice versa. You wouldn't normally think of it that way, but that is nevertheless what happens. The zero-sum nature of money doesn't disappear just because the competitive dynamics are indirect.

The greenfield advice is still good advice. Creative destruction is genuinely how the world moves forward. It's good for the winners, good for the consumers of the new market, and bad for whoever gets displaced. But the advice has a hidden prerequisite that most greenfield evangelists gloss over.

The prerequisite nobody talks about

To do greenfield work, you need to see something the rest of the world doesn't. Either you can envision an end state that others can't picture, or you can envision a path to an end state that others can picture but can't reach.

Sometimes the end state is trivial to imagine—electric cars, reusable rockets—but the path is exceedingly hard. Sometimes even the end state is non-obvious.

Either way, the necessary ingredient is exceptionality. You have to perceive something that others don't. And by definition, that can't be true of everyone simultaneously. If everyone saw the same opportunity, it wouldn't be a greenfield—it would be a crowded market.

So the advice "play non-zero-sum games" quietly reduces to "be exceptional." And while that's individually useful, it's structurally useless as policy, because most people—by mathematical necessity—will not be the one who sees what others don't. Most people will be playing zero-sum games most of the time.

This isn't doom and gloom

You don't have to be the world's best soccer player to enjoy soccer. You don't have to be the one who sees the greenfield to live a good life. Human flourishing doesn't require winning.

But talking about the zero-sum question honestly requires acknowledging what both sides are sweeping under the rug:

The entrepreneurs are right that value creation is real, and wrong to dismiss the concentration of monetary power as irrelevant.
The populists are right that structural unfairness exists, and wrong to think redistribution alone fixes the mechanism that produces it.
The greenfield evangelists are right that creative destruction drives progress, and wrong to pretend it's a strategy available to everyone equally.

The actual leverage point—the thing that would shift the most—is making more people capable of participating in the growing parts of the economy. That means better education. Not more education, which has been the default answer for decades. Better education. And in some cases, better might mean less. This should really be the continual quest of education: How can we teach the same amount of stuff in less time? But that is debate for another day.

Where the interesting question actually is

You can't point to where truth is explicitly. But you can usually point to what you don't know for sure yet.

The productive version of this debate isn't "the world is zero-sum" versus "the world is not zero-sum." It's: where is the boundary between the two, and what moves it? And if that's the real question, then the arguments that inherit from it—the housing debate, the wealth tax debate, the immigration debate—are probably not productive either, at least not in the form we're having them. They're arguing over consequences while the underlying disagreement about mechanism goes unexamined.

Better questions might be: what makes a game zero-sum in practice versus in theory? What would it take to let more people participate in the parts that are genuinely expanding? Those seem more worth arguing about.
