Labor shortages do not justify immigration restriction as a wage-protection tool
Labor shortages in low-wage sectors justify immigration restrictions to force wage increases and protect domestic worker employment.
Native worker wage elasticity to immigration sits near zero (-0.1 to +0.1 in Borjas and Card's estimates), and restriction episodes in the UK, Australia, Hungary, and Poland all failed to produce sustained real wage gains in the targeted low-wage sectors; immigrants and native workers function largely as task-complements rather than substitutes, so restricting labor supply reduces productivity and output without delivering the promised wage floor.

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 and Card's wage-elasticity estimates put the native-worker effect of immigration at -0.1 to +0.1, far below the magnitude needed to justify restriction as a wage-protection strategy.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The restriction-raises-wages mechanism assumes immigrants and natives are substitutes in a frictionless labor market, but Peri & Sparber's task-complementarity findings and observed upstream inflation and automation responses break this causal chain at multiple points.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Labor economists studying immigration and wages broadly reject restriction as an effective wage-protection lever, attributing low-wage stagnation instead to union decline, capital concentration, and skill-biased technological change.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
The no-sustained-wage-gain finding replicates across the UK's post-Brexit points system, Australia's skilled-migration tightening, and Hungary's and Poland's restrictive policies, each showing stagnant or declining real wages in the targeted sectors.
