## Statement

Restoring the inheritance-tax framework that existed pre-1981 — substantially lower exemption thresholds, the elimination of step-up-in-basis at death, closing the dynasty-trust route — addresses the intergenerational component of wealth concentration directly. Historically, the US compression of top-wealth shares between 1930 and 1980 tracked the rise of estate taxation; its erosion since 1981 tracked the renewed rise.
