Immigration suppresses wages for native-born workers
Increased immigration, especially low-skilled immigration, increases the labor supply and suppresses wages for native-born workers competing for the same jobs.
The wage-suppression claim has genuine empirical support in a narrow band: high school dropouts face modest wage competition from low-skilled immigrant labor, and the Borjas reanalysis of the Mariel Boatlift produced credible estimates of that effect. But the full picture is more complex — most economists find small or near-zero average native wage effects, immigrant and native labor are frequently complements rather than substitutes, and the fiscal and innovation contributions of immigrants are positive at the college-educated margin. The claim is selectively true but systematically overstated when applied to workers broadly.

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.
Borjas's Mariel Boatlift reanalysis finds a genuine wage effect for high school dropouts, but most economists find near-zero average native wage effects across the broader labor market.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The labor-supply-competition mechanism holds for a narrow low-skill segment, but immigrant and native labor are frequently complements rather than substitutes, limiting the mechanism's scope.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Most labor economists find the wage-suppression effect real but confined to a narrow low-skill margin, disputing the claim's broader application.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
The dropout-wage-competition finding replicates in some studies (Borjas) but not others (Card), reflecting a genuinely contested, narrow-effect literature.
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 →
