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 — same $6,300B Distributed Healthcare basis, with revenue stressed below central through the transition (no offsetting multiplier). Debt Sunset steps rates to the corridor ceiling (payroll 29.00%; top rate 53.00%) and holds until pressure eases. Debt retired ≤2079 by statute; ~2060 projected — inside the 50-year corridor.
Central scenario — Distributed Healthcare basis $6,300B. Debt Sunset mostly inactive. payroll tax near 28.00%; top rate near 52.00%. Debt retired ≤2079 by statute; ~2058 projected.
Optimistic scenario — Distributed Healthcare basis $5,010B. Debt Sunset steps downward to the corridor floor (payroll 25.00%; top rate 49.00%). Debt retired ≤2079 by statute; ~2044 projected.
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.
