For-profit hospitals are not that important (~20% of the hospital system). Edit: But if lawyers can make it to that list hospitals can as well (including not-for-profit hospitals paying huge salaries, just because they are not “for profit” it doesn’t mean they are not profit-driven).
Non-profit hospitals are responsible for the bulk of health care costs, they just extract the profits in salaries.
Calling salaries extraction of profits is a weird way of spinning people being paid for their work. Even the most egregious executive and administrator salaries are small potatoes on a hospital’s balance sheet.
