From your second link, except in the last year, healthcare spend has been outpacing inflation by more than 2 to 1. The economics of scale are backwards in healthcare, I find that perverse.
I think we can agree that something will need to change as medical trend cannot outpace inflation forever. I don't think the issue is with executive compensation, because even if insurance companies magically could perform all their services for free, you would only reduce premiums by less than 20%.
UnitedHealth total comp have been rising for C levels, except the CEO who recently left, who stayed around 17mil. https://www.salary.com/tools/executive-compensation-calculat...
