Why gross cost is not net cost

Every discussion of basic income arrives, sooner or later, at the same moment: somebody multiplies the monthly amount by the number of inhabitants, produces an enormous number, and considers the matter closed.

That calculation is wrong, but not in the way supporters of basic income sometimes imply. It is not wrong because the spending is trivial. It is wrong because it measures the wrong thing.

What the multiplication actually measures

Amount times population gives the gross flow: the total of the payments that would leave the treasury. It is a real number, and it is useful for sizing the administrative operation.

It is not, however, the cost to the public finances, because a substantial part of that money returns immediately through the tax system.

An example makes it clear. Imagine two people: one with no income and one with a high income. Both receive the same basic income. The first keeps all of it. The second receives it, but pays tax that — if the system is designed for it — rises by an amount equal to or greater than what they receive.

For the second person the operation is, from the point of view of the public accounts, a book transfer: the state pays out a thousand and takes back a thousand. The gross flow records two thousand in movements; the net cost is zero.

The effective cost of a basic income is therefore the sum of what stays in the pockets of people who do not return it through tax. That is far below the gross figure, and the difference is not marginal: it changes the order of magnitude.

The second item: what it replaces

A basic income does not arrive on an empty table. It arrives in systems that already pay cash benefits: income support, basic unemployment allowances, social pensions, minimum top-ups.

Part of those benefits perform exactly the same function as a basic income — guaranteeing a minimum — with the addition of verification bureaucracy. That part can be absorbed, and its current cost subtracted from the total.

So can the administrative cost of running them: offices, staff, information systems, litigation. It is an item that rarely appears in comparisons, because it is spread across many different budgets and nobody adds it up.

But be careful not to overreach in this direction, because that is the mirror-image error. Not all existing benefits can be absorbed: those tied to specific needs — disability, long-term care, particular medical situations — must remain, because they answer costs that a sum identical for everyone does not cover. Anyone presenting basic income as a replacement for the whole welfare state is proposing something else, and should say so.

What remains to be covered

After removing the book transfer and the absorbed benefits, an amount remains. And it is large.

This is the point where honesty matters more than persuasion: a basic income sufficient to live on requires significant additional resources. No version of the proposal finances itself. Anyone arguing otherwise weakens their own position, because the first serious objection dismantles everything else with it.

The routes discussed for covering the difference are known and each has real problems.

Revising income taxation is the most direct and the most coherent with the mechanism: if the basic income is recovered progressively, increasing progressivity is part of the design. The limit is political before it is technical.

Wealth taxation appears in almost every proposal. The known limit is capital mobility, which makes it hard for a single country to act alone — and is one of the arguments for the European level.

Taxing capital income at parity with labour income is technically simpler and politically contested for decades.

Proposals on the profits of automation are the most discussed in relation to artificial intelligence and the least defined: identifying what exactly counts as a profit generated by automation, and distinguishing it from ordinary business profit, is a problem nobody has solved convincingly.

The question that is missing

There is a way of framing this that the debate neglects, and that is more useful than trading figures.

The question «how much does it cost?» assumes the alternative is zero. It is not.

Today we spend on unemployment, on income support, on the health consequences of prolonged precarity, on running conditional systems and on the litigation they generate. We also spend, less visibly, in economic activity that never happens: people who do not start a business because they cannot afford to be wrong, who do not change jobs, who do not retrain.

An honest comparison does not set basic income against zero. It sets it against the cost of the current system, plus the cost of what that system will produce if the labour market keeps fragmenting.

This does not solve the financing problem, and it is not an elegant way of dodging it. It does move the discussion from ground where it cannot be won — «it's a lot» — to ground where it can be conducted: which of the two configurations costs less, counting everything.

Why European budget rules complicate this

There is an obstacle that rarely enters the debate and weighs more than many theoretical objections: European fiscal rules.

A basic income is, in public accounting, current expenditure. It is not investment, not one-off, and has no end date. That means its net cost enters the accounts the Union monitors in full and permanently, and a country close to its deficit limits cannot introduce it without structural, credible fiscal cover.

This has an important practical consequence: no national government can seriously trial basic income as a temporary measure financed by borrowing. That is not a political choice, it is an accounting constraint.

It is also one of the most concrete arguments for European action. A common framework could define how the measure is treated in the accounts, provide shared financing instruments for a trial phase, and relieve individual member states of carrying both the cost and its accounting treatment alone.

An order of magnitude, with all the caveats

A fair question is: roughly how much are we talking about?

This site does not answer with a figure, and it is worth explaining why. Every serious estimate depends on four choices nobody has yet made: the amount, who receives it, which benefits are absorbed, and how it is recovered through taxation. Change one of those four and the result moves by orders of magnitude.

The figures circulating in public debate — the frightening ones and the reassuring ones alike — are almost always built by fixing those four choices in whatever way suits the case being argued.

The honest answer is that the cost depends on the design, that the design does not yet exist, and that writing it is precisely what is being asked of the European institutions. That is not an evasion: it is the only way of not doing what we criticise in others.

A warning to people making the case

If there is one point where supporters of basic income lose credibility, this is it. The estimates in circulation are often built by choosing the most favourable assumption on every single item, and the result is a number no serious economist recognises.

It is a way of arguing that works with the already convinced and fails with everyone else. The stronger position is not to demonstrate that it costs little, but to admit that it costs and argue that it is worth it — stating precisely where the money comes from and who will pay more.

That is a harder conversation. It is also the only one that can lead anywhere.

A note on the figures

This site publishes no estimate of what a European basic income would cost, and the omission is deliberate. Every serious estimate depends on four choices nobody has yet made: the amount, who receives it, which existing benefits are absorbed, and how much is recovered through taxation. Change one and the answer moves by an order of magnitude.

The figures circulating in public debate — the alarming ones and the reassuring ones alike — are almost always constructed by fixing those four choices in whatever way suits the case being made. That is a way of arguing that works on people already persuaded and fails on everyone else.

The honest position is that the cost depends on a design that does not yet exist, and that producing that design is precisely what is being asked of the European institutions.

In brief

This article addresses one part of the problem, not the problem. A basic income creates no jobs, teaches no trades, does not fix pensions and does not replace the services that answer unequal needs. The claim argued on this site is narrower: that it is, among the available instruments, the one that makes the others workable. Training requires being able to live while training; changing occupation requires being able to be wrong; refusing indecent conditions requires being able to afford refusal.

Three objections remain standing, and this site gives each of them a page: the cost, which is real and requires serious fiscal choices; the effect on rents in markets with inelastic housing supply; and the absence of a credible transition plan. None of them shows the proposal is wrong. All three show it is not ready, which is why the demand made here is not immediate introduction but a serious European trial and a public study putting costs, routes and losers on the table.
