SES as genetic sorting mechanism

Socioeconomic status functions as a dynamic social filter: people with genetically influenced traits that help secure status are non‑randomly sorted into strata where different environments then feed back on reproduction, health and mating patterns. Over generations that sorting can change the regional and familial distribution of trait‑associated alleles, meaning social policy shapes not just opportunity but the genetic composition correlated with outcomes. — If true, this reframes debates about inequality and policy: remedies must consider how social structure both reveals and produces biological differences, and guard against deterministic or discriminatory uses of genetics.
