Public Debt Trajectory Simulator

The Evil Formula made visible: $1.x > $1, for every x > 0.
Adjust the parameters. Watch the compounding. Then ask yourself why this is considered normal.

MODEL: Debt(t+1) = Debt(t) + Debt(t) × interest_rate + GDP(t) × primary_deficit%
PCM SCENARIO: interest_rate = 0 (F.V.I. direct Treasury issuance) + primary_deficit = 0

HYPOTHESIS: constant average interest rate, constant nominal GDP growth rate, constant primary deficit as % of GDP over the entire period. Real dynamics are non-linear.
ESTIMATE: USA 2026 default values sourced from US Treasury, BLS, CBO (May 2026). Other scenarios are illustrative.
PCM SCENARIO: F.V.I. (Fungible Value Index) issued directly by the Treasury, zero financing cost, zero primary deficit. This is not a prediction. It is a structural simulation showing what the Evil Formula ($1.x > $1) does over time, and what eliminating it would mean mathematically.
