The case for universal basic income has never been stronger.
Pilots in Finland, Kenya, Stockton, and dozens of other places have shown the same things: financial stability improves, health improves, people don’t stop working. The evidence is solid. Anyone who still dismisses UBI research hasn’t read it.
But there’s a question the movement keeps stepping around. Not “does it work” — it does. The question is: where does the money come from, and what happens to it when you need it most?
That question has a structural answer. Most UBI conversations never get there.
The Wrong Unit of Analysis
Every serious UBI proposal eventually runs into the same wall: cost.
Tax-funded UBI at any meaningful level requires governments to collect and redistribute enormous sums annually. Finland’s modest pilot — €560 a month to 2,000 people for two years — worked precisely because it was small. Scaling it to every adult in Finland would cost roughly 5% of GDP, according to the country’s chief trade union economist. Scale it to every adult on the planet and national tax bases collapse as the unit of analysis entirely.
World GDP reached $111 trillion in 2024. There are roughly 6.5 billion adults on earth. A payment of even $50 a month to every adult — modest by any rich-country standard, transformative by the standard of the 700 million people living on less than $2.15 a day — would cost around $3.9 trillion annually. That’s nearly 3.5% of all economic activity on the planet, sourced from national tax systems that already struggle to fund schools and hospitals.
This is not an argument against universal income. It’s an argument that national tax revenue is the wrong base for something planetary.
The Timing Problem
There’s a second flaw that goes unmentioned even more often.
Tax-funded programs move in the wrong direction when crises hit. When an economy contracts — a pandemic, a financial crash, a drought — tax revenues fall. Governments face deficits. The political pressure is to cut spending, not expand it. The moment people need income support most is precisely when tax-funded programs face the most pressure to shrink.
We saw this in 2008. We saw it in 2020, when emergency cash transfers were extraordinary one-time measures, not a functioning system. We see it repeatedly in developing economies, where IMF conditions during crises often require cutting social spending at the worst possible time.
A program that calls itself universal and basic cannot have a funding source that fails in emergencies. That’s a design flaw, not a political problem. Changing the government doesn’t fix it.
A Different Base Entirely
The commons — the atmosphere, the accumulated knowledge inside every technology, the behavioral data generated by billions of people going about their lives — are used by businesses everywhere to generate revenue. Every day. Without payment.
A mining company in Chile extracts copper from land that no person invented. A pharmaceutical company in Switzerland builds on decades of publicly funded research. A platform in California earns billions targeting advertising using behavioral patterns collected from people in Lagos, Jakarta, and Sarajevo. Three inputs. Three commons. None of them on the invoice.
Carbon pricing shows what happens when you start putting them on the invoice. In 2023, 75 carbon pricing instruments operating across the world generated a record $104 billion in revenue, according to the World Bank. That’s from pricing just one commons — the atmosphere — and covering only 24% of global emissions. The royalty base grew automatically as economic activity grew. It didn’t require an annual parliamentary vote. It didn’t shrink during the pandemic the way income tax receipts did. It collected at the point of use.
That is the architecture. Not redistribution funded by taxing people after the fact. Royalties collected upstream, at the gates where money already moves — customs offices, financial exchanges, licensing authorities, digital platforms — and returned equally to every person.
Why This Holds Where Tax Revenue Doesn’t
A royalty on commons inputs moves in the right direction when the economy moves. When global trade expands, more resources cross ports and more royalties accrue. When the technology sector grows, more knowledge-intensive revenue flows through exchanges. When digital advertising rises, more behavioral data is being priced. The base grows with the economy.
More importantly, it isn’t owned by any single government. The commons are planetary. The atmosphere doesn’t belong to Germany or Brazil or Bosnia. The knowledge embedded in a smartphone was built by researchers on every continent over a century. The data powering AI models came from billions of people who never consented to contribute it for free. These are shared inputs. Their royalty belongs to everyone who shares them — which is everyone alive.
The governance model for this already exists. Norway’s Government Pension Fund manages over $1.7 trillion in assets through an independent board, transparent public reporting, and rule-based payouts strictly separated from the annual political budget. Alaska’s Permanent Fund has paid every resident a share of oil royalties for over four decades, across governments of every political stripe, because people understand it as theirs — not as a benefit that might be taken away. The mechanics aren’t new. What’s new is applying them to the three commons that underpin the entire global economy, not just one oil field.
The Real Question
When people ask how to pay for universal basic income, they are usually imagining a national government writing checks funded by national taxes. That framing makes the cost seem impossibly large and the politics impossibly fragile.
Change the frame. The commons are global. The royalty base is global. The fund is global. The dividend is equal — not equal within one country, but equal across every person enrolled, from Oslo to Nairobi to Sarajevo.
The funding problem isn’t an argument against universal income. It’s a sign that the movement has been looking at the wrong source.
The chapter on the fund in Shareholder at Birth walks through how this actually works — the gates, the payout math, the governance structure, and what a household could realistically expect month to month. The section on upstream invoicing covers why collection at existing chokepoints solves what downstream redistribution keeps failing to fix.
