Tax cuts pay for themselves through economic growth
Reducing tax rates stimulates so much economic growth that government revenue actually increases — the Laffer Curve effect means tax cuts are self-financing.
No major US tax cut has produced revenue neutrality: Kansas's supply-side experiment collapsed in 5 years, the TCJA produced a $1.46 trillion JCT-scored deficit increase, and cross-national OECD data show no correlation between tax burden and growth rates, definitively falsifying the claim that rate reductions self-finance through behavioral responses.

Premise Assessment
Is the claim as stated true? Four dimensions, each 0–25, sum to 100. The verdict label is derived from this score. Full rubric →
Quality and quantity of direct evidence for or against the claim — RCTs, systematic reviews, natural experiments, large cohort studies.
Kansas's supply-side tax cut collapsed within 5 years and the TCJA produced a $1.46 trillion JCT-scored deficit increase, directly contradicting the self-financing claim.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The Laffer-curve self-financing mechanism requires rates far above any actual US bracket to hold, and OECD cross-national data show no correlation between tax burden and growth, debunking the proposed pathway.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Economists across the political spectrum, including the JCT's own scoring, reject the strong self-financing version of the Laffer Curve.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
Every major US tax-cut episode studied (Kansas, TCJA, 1980s federal cuts) has failed to replicate revenue neutrality.
Individual vs. Structural
How much of the outcome is explained by structural forces versus individual agency? Four dimensions, each 0–25. Higher scores indicate stronger structural causation. Full rubric →
