Advocates point to specific historical policies — slavery, Jim Crow segregation, discriminatory redlining in housing — as concrete, documented mechanisms that contributed to lasting wealth disparities. Redlining, a federally sanctioned practice that denied mortgages in Black neighborhoods for decades, is specifically cited as a policy with directly traceable effects on homeownership and wealth accumulation that persist today. Advocates argue this direct causal chain, from policy to present-day outcome, distinguishes reparations from a purely symbolic gesture. They see the historical record as strong enough to support concrete redress.
