So we try to make an end run around scarcity with things such as health insurance and government medical plans, both of which are based on the same economic principle: Someone else pays.

They put you on a waiting list and hope you die before they actually have to say “No,” or they simply expect you to accept that some services and treatments are categorically unavailable. There is a reason New York City’s hospitals are full of rich Canadians who cannot afford the free health care at home.
