The Fifty-Year Fiscal Promise

Version: v10 · Canonical source: naa_canonical_parameters_v10.md

Framing

The Accord retires the federal debt within 50 years. This is an architectural guarantee, not a forecast dependent on favorable conditions. The Debt Sunset macrogovernor automatically adjusts payroll tax and top income tax rates together, within statutory corridors, whenever the Year N+4 fiscal projection drifts off target.

The canonical scenarios

Conservative scenario — Distributed Healthcare basis $6,250B. Debt Sunset triggers upward. payroll tax peaks at 29.00%; top rate at 56.00%. Debt retires approximately 2095.

Central scenario — Distributed Healthcare basis $5,900B. Debt Sunset mostly inactive. payroll tax near 28.00%; top rate near 55.00%. Debt retires approximately 2079 (Year 50, counting 2030 as Year 1).

Optimistic scenario — Distributed Healthcare basis $5,550B. Debt Sunset triggers downward. payroll tax drops to 26.50%; top rate to 53.50%. Debt retires approximately 2055.

The architectural lock

In every scenario, debt retires within 50 years. The difference is what tax burden households bore along the way. Debt Sunset's trigger is cause-agnostic — it responds to projected fiscal drift regardless of source.
