Transparency about what we're assuming and the risks if we're wrong
Average annual growth (vs 2.0% baseline)
Point-of-sale collection minimizes evasion (vs 15% current income tax gap)
Administrative savings from universal coverage

Each assumption has been stress-tested with ±20% variation:
| Assumption | Base Case | -20% Scenario | +20% Scenario | Impact |
|---|---|---|---|---|
| GDP Growth | 3.2% | 2.56% | 3.84% | ±$1.2T Year 30 revenue |
| GRT Evasion | 5% | 4% | 6% | ±$300B Year 1 revenue |
| Healthcare Costs | $3.5T | $2.8T | $4.2T | ±$700B annual spending |
| Alliance Growth | 730M | 716M | 1.07B | ±$2T Year 30 GDP |
| Stability Account Returns | 6.88% | 5.5% | 8.25% | ±$400K avg retirement |
Risk: Framework requires constitutional amendments and major legislation
Probability: 40-50% with proper execution
Mitigation: Coalition building across political spectrum, phased implementation, state-level pilots
Risk: Moving from current tax system to GRT causes economic disruption
Probability: High in Year 1-2
Mitigation: 3-year transition period, grandfather provisions, immediate benefits offset costs
Risk: Universal coverage costs more than projected
Probability: Moderate (±15% uncertainty)
Mitigation: Phased rollout, cost controls, efficiency gains from preventive care
Risk: GRT collection integration with existing payment systems faces delays
Probability: Moderate
Mitigation: Phased rollout, state-level pilots first, leverage existing Visa/Mastercard/bank infrastructure
Risk: Other nations oppose Alliance formation
Probability: Variable by nation
Mitigation: Voluntary participation, demonstrated benefits, bilateral agreements first
The framework does NOT depend on:
What has to be true for this to work—and where it could fail
Bootstrap Challenge: Programs build voter support, but you need political will first to create programs.
All of this happening exactly as described? Low.
Core economic logic being sound? That's what we're testing.
Some version of this becoming necessary? Increasingly likely as systems strain.
This isn't a prediction—it's a framework to have ready when extraordinary conditions emerge.
