Data shows yes on both metrics for the remaining population. Blacks are ~13.5% of the US population. FBI 2025 data: they account for 55% of known murder offenders and ~30-43% of violent crime arrests. Homicide and robbery rates would fall sharply (most crime is intraracial). Median Black household income is ~$60k vs ~$97k for non-Hispanic Whites. Black wealth share is ~3-4%. They are overrepresented in SNAP (~26%) and TANF (~28%). Net fiscal contribution is lower; crime and incarceration impose large costs. Total GDP would shrink ~8-10%, but per capita income, wealth, and safety would rise as lower-output groups and associated burdens are removed.
