I suggested we take him to the hospital. He refused. "I can't afford that. They're already chasing me for $16,000". He worried that they'd refuse to treat him. I informed him that legally, they were obligated to, but of course that would cost money.
In the end, he stayed home. His wife promised to either call us again if he got particularly worse, but both of them were reluctant, even then, for him to go via ambulance - "At least that way we can save about $1,000".
It is a sad day in a civilized, modern society when fundamental decisions on healthcare are made purely on finances, not quality of life.
