Abstract
Public discourse often attributes a wide range of social problems—crime, unemployment, housing shortages, fiscal strain, cultural decline—to immigrants as a single causal explanation. This commentary critiques what I call the omnibus immigrant-blame thesis: the claim that immigrants are responsible for “everything” or for most major social ills. The critique is both logical and empirical. Logically, the thesis fails standards of specificity, falsifiability, proportionality, and mechanism; it commits scope inflation, base-rate neglect, composition and single-cause fallacies, and often relies on ecological and confounding errors. The fact that immigrants are usually a numerical minority does not make them morally immune from criticism, but it does impose a strict burden of causal evidence on omnibus blame: for a small group to explain a large aggregate problem, per-capita effects would have to be implausibly large and would need to be demonstrated, not assumed. Empirically, research on labor markets, crime, housing, and public finance finds context-dependent and heterogeneous effects, not a general pattern of “everything.” Social-psychological research explains why scapegoating persists: group threat, availability cascades, illusory correlation, and media amplification. The commentary concludes that blanket immigrant blame is not a scientific theory but a rhetorical attribution schema. Legitimate policy debate should be disaggregated by outcome, mechanism, time scale, and local context.
