Apparently many US hospitals are formally non-profits but operate very much in a corporate logic. What did mayo do with its bn profit last year that Op mentioned?

Mayo earns $12bn per year.

As contrast, a hospitals in Germany for a whole year cost €105bn, with an average total cost per stay (including operations etc ) of 4500€.
