  "headline": "Starting from today's concentrated wealth, EDEN's Legacy Assets ERODE dynastic concentration: wealth Gini and the top-1% share fall toward the income-driven level, and the gen-0 top decile loses its grip (persistence decays toward the full-mobility line). The money-machine regimes do the opposite - inherited, compounding capital keeps the SAME families on top, so concentration and persistence stay high (Today, financial capital, most of all; No-Legacy less, because EVE freshness-decay fades inherited assets). EDEN's residual is bounded MERITOCRATIC persistence from human-capital transmission (rho), which rises gently with rho but never locks in like compounding capital. The fourth line is a COUNTERFACTUAL, not an EDEN config: it asks what would happen IF a dead owner's dependency royalties were inherited (they are NOT - Legacy stops ALL earning at death, direct and dependency). That counterfactual re-creates PARTIAL dynasties (persistence ~54%) even while headline inequality looks benign (top-1% ~10%) - which is why it matters that Legacy zeroes dependency earning too, and why the orphaned dependency-share of a LIVE asset whose dependency is now Legacy routes to the FLOOR (not heirs, not the living stack). Verdict: SURVIVES on the core anti-dynasty claim WITH ONE FIX; state it precisely: 'capital dynasties dissolve; position advantage persists but is bounded and does not compound.'",
