What happens to a country's social contract when anyone can enter it without consent?
That's the real question here. Open borders aren't just a policy preference—they're the elimination of the nation-state as a meaningful unit. A country is defined by shared obligations: taxes fund schools, hospitals, infrastructure. Those obligations only work when membership is bounded. If borders are open, the welfare state collapses under its own generosity. You can't promise universal healthcare to the world on a budget designed for your citizens.
We also ignore the strain on wages and housing. When labor supply spikes overnight, employers gain leverage and workers lose it. That hurts the poorest citizens most.
Open borders sounds compassionate in theory. In practice, it's a mechanism that dissolves democratic accountability. Citizens lose the ability to decide their own future. That's not progress—it's abandonment of governance. Controlled borders aren't cruelty. They're the basic framework that makes any social system functional.
