The Sufficiency Guarantee

What the Guarantee Is

Every person within a TEH economy — regardless of earning capacity, employment status, or life circumstance — is guaranteed sufficient TEH to meet their registered entropy obligations. Not as charity. Not as a welfare program. Not as a discretionary benefit that can be expanded in good times and cut in bad ones. The Sufficiency Guarantee is a constitutional commitment: a structural floor beneath which no member of the collective is permitted to fall.

The guarantee has two components.

The first is EOH reimbursement — TEH sufficient to cover the biological entropy burden of being alive. Every person generates personal entropy obligations simply by existing: food, water, shelter, warmth, sanitation, healthcare. These obligations are age-weighted (a child's needs differ from an adult's, which differ from an elderly person's) and reduced to the extent that automated capital systems already fulfill some of those needs directly. What remains — the unfulfilled personal EOH that still requires goods and services purchased with TEH — is covered at one TEH per unit.

The second is a meaningful activity stipend — additional TEH available to individuals engaged in formal labor, recognized care labor, retraining, disability accommodation, or retirement. This stipend is not a luxury bonus. It reflects the framework's recognition that human participation in the collective — in whatever form a person's circumstances allow — is itself a contribution worth supporting. The stipend grows as automation rises, ensuring that people who are not in the formal labor force gain real purchasing power as the economy progresses, without eliminating the incentive for those who do work (workers earn their multiplier premium on top of the guarantee).

Together, these two components define a floor of real sufficiency: not bare survival, but a standard of living anchored to what the physical world actually demands to keep a person healthy, sheltered, and participating in civilization.

Who Receives It

The guarantee is available to every member of the collective, but it is not a universal flat payment. It is calibrated to the gap between what a person earns and what they need.

A worker earning well above sufficiency through their own labor does not draw on the guarantee — their income already exceeds the floor. A worker earning just below sufficiency receives the difference. A person unable to work — due to disability, age, care commitments, or a period of retraining — receives the full guarantee amount. The floor catches everyone at the same level regardless of the reason they need catching.

The fraction of the population actually drawing on the guarantee declines as automation rises and general purchasing power increases. At high ε, most people earn enough through even modest labor to exceed the floor. But the framework maintains a structural minimum — at least 5% of the population is always covered — because at any point in the arc there will be people in training, recovering from illness, providing full-time care, or transitioning between roles. The guarantee does not assume a perfect workforce. It assumes a human one.

Why the Floor Only Rises

This is the feature that separates the Sufficiency Guarantee from every welfare program, minimum wage, or basic income proposal in a fiat economy: the floor rises automatically with automation, and it cannot fall.

The mechanism is not political. It is mathematical.

The guarantee is denominated in TEH. The goods and services that make up the sufficiency basket — food, housing, healthcare, energy, basic transport — are also denominated in TEH. As automation increases and ε rises, the human labor content of those goods falls. TEH-denominated prices drop. The same nominal TEH buys more real goods.

A sufficiency basket that costs 2,080 TEH at ε = 0.40 might cost 1,500 TEH at ε = 0.60 and 500 TEH at ε = 0.90. The guarantee amount may stay constant in nominal terms while the real standard of living it provides grows steadily. The floor rises not because anyone voted to raise it, but because the currency honestly reflects the declining human labor cost of meeting basic needs.

The framework enforces this with a monotonicity guard — a formal check that sweeps across the entire automation spectrum and hard-fails if any step shows the floor's purchasing power declining. This is not a policy aspiration. It is an algebraic constraint built into the system's verification layer. If a proposed change to any mechanism would cause the floor to fall at any point on the arc, the system flags it as a structural violation before it can be implemented.

In a fiat economy, the floor is whatever the legislature last set it at, denominated in a currency that loses value every year. In HOURS, the floor is a mathematical consequence of honest prices and a stable unit — and it only moves in one direction.

The Trust: What Holds the Floor Up

A guarantee is only as good as the institution that funds it. In the HOURS framework, that institution is The Trust — a collective account that holds accumulated social wealth and funds the civilization's structural obligations.

The Trust is not a sovereign wealth fund in the fiat sense. It does not invest in assets that generate returns. It cannot earn interest — Condition III prohibits it. It does not grow through financial engineering. The Trust's balance changes through exactly two channels: levy inflows add to it, and payouts draw from it. Nothing else. The simplicity is the point — there is no mechanism for the Trust to paper over a shortfall by creating money, borrowing against future revenue, or leveraging its balance. What it has is what it can spend.

Revenue flows into the Trust through levies — a share of labor income redirected from workers to the collective account. Levies are strictly circulatory: they move TEH from one part of the system to another without creating or destroying it. Every TEH collected in levies is a TEH that a worker earned through verified labor. The ledger identity holds throughout — total TEH in existence equals total TEH created minus total TEH destroyed, and levies appear in neither column.

The Trust's spending capacity is governed by a depreciation draw — a controlled rate at which accumulated social wealth is mobilized for current obligations. A fraction of the Trust's balance is made available each period. Of that available amount, a portion is paid out as dividend to fund obligations, and the remainder stays in the Trust as renewal — maintaining the balance against its own gradual drawdown.

Three Co-Equal Obligations

The Trust funds three categories of structural obligation, each sized against physical reality rather than political budgeting.

Stewardship allocation funds the labor required to maintain the civilization's infrastructure — its roads, bridges, power grids, water systems, communication networks, and all other built capital. The allocation is sized by infrastructure EOH: the actual entropy obligations generated by the capital stock, measured through engineering assessments and physical monitoring. As automation grows and the capital stock expands, stewardship obligations grow with it. The Trust doesn't decide how much to spend on infrastructure maintenance — the physical world decides, and the Trust funds the answer.

Ecological allocation funds the labor required to maintain natural systems the civilization depends on — soil fertility, water cycles, pollination networks, fisheries, forests, climate stability. Like stewardship, this allocation is sized by ecological EOH: the measured entropy obligations of the ecosystems within the collective's responsibility. At high automation, the remaining human labor in this domain is judgment-intensive — triage, intervention, monitoring — work that automated systems cannot fully substitute for. The ecological allocation ensures this work is funded regardless of whether the broader economy is booming or contracting.

Sufficiency Guarantee is the third obligation, co-equal with the other two. It is not the residual — not what's left after infrastructure and ecology have been funded. All three draw from the full Trust balance independently. The guarantee is sized by the population's registered needs, the current basket price, and the meaningful activity stipend. It is as structurally fundamental as keeping the bridges standing and the soil fertile.

Care labor — the work of raising children, educating, healing, and mentoring — enters the fiscal architecture as a recognized obligation alongside these three. As the collective's dependence on quality human capital grows with automation, the share of care labor admitted to the ledger and funded through the Trust expands along a sigmoid curve, progressively recognizing what was always happening but was previously invisible to the formal economy.

The Solvency Question

Here is where the HOURS framework is most honest — and most demanding.

In a fiat system, fiscal solvency is never truly at risk because the monetary authority can always create more currency. The cost of that creation is inflation, debasement, and erosion of purchasing power — but the books balance because the system can always print its way out of a deficit. The solvency question in fiat is not "can we pay?" but "what does paying cost everyone else?"

In HOURS, solvency is a genuine physical constraint. TEH cannot be created without verified labor. The Trust cannot print its way out of a shortfall. If levy inflows are insufficient and the Trust's balance draws down, it draws down for real — and if it reaches zero, the structural obligations it funds are unfunded.

This creates a long-run design requirement that the framework does not hide from. As ε rises toward post-scarcity, two things happen simultaneously. Labor income approaches zero (because almost no human labor is needed), which means levy revenue approaches zero. But obligations do not reach zero — stewardship costs decline as automation handles more maintenance, but the Sufficiency Guarantee's meaningful activity component actually grows, and ecological obligations persist. At very high automation, the Trust must be self-financing: its accumulated balance and depreciation draw must cover obligations without significant levy support.

This means the Trust must be built up during the transition — during the centuries or decades when labor income is substantial and levy revenue is flowing — to a level sufficient to sustain itself through the endgame. The framework provides explicit tools for modeling this trajectory: multi-period solvency simulations that expose slow drawdown invisible in any single period, inverse queries that compute the minimum levy rate needed to keep the Trust stable at any given ε, and minimum dividend calculations that determine what the Trust's own depreciation draw must cover.

The solvency question is genuinely open. The framework models it as a testable structural property — something you can simulate, stress-test, and verify — not something assumed away.

The Expanding Floor

As a civilization advances along the automation arc, the Sufficiency Guarantee does something no fiat welfare system can replicate: it expands its scope automatically.

At low ε, the guarantee covers basic biological needs for those who cannot meet them through their own labor — a safety net in the traditional sense, modest and targeted. As automation rises and the collective's capacity to fulfill EOH grows, the system's relationship to its members deepens. More categories of personal EOH move onto the collective ledger. More forms of care labor are recognized and compensated. The meaningful activity stipend grows, reflecting the collective's increasing ability to support human flourishing beyond bare survival.

At high automation, the guarantee approaches something that looks less like a safety net and more like a birthright — every member of the collective has their basic entropy obligations met by systems the collective built and maintains, and the stipend provides genuine participation in the economy's abundance. The requirement flows in both directions: the system expands its commitment to its members, and membership in the system carries obligations — the 260-hour minimum, the competency maintenance, the willingness to surge when the collective needs it.

This is not post-scarcity utopianism. It is the logical conclusion of a system that tracks entropy honestly, funds its obligations from real wealth, and measures progress by how thoroughly a civilization has liberated its people from the physical demands of survival. The floor rises because the prices fall. The prices fall because the machines take over the work. The machines take over the work because that is what ε measures. And at every point along the arc, the guarantee holds — not because a government chose to fund it, but because the architecture makes it inescapable.
