FWIW there are some studies that try to break apart health outcomes caused by health care vs those cased by lifestyle. Most of these seem to indicate that we are actually getting something for our extra money in the US. Cancer recovery rates, for example, are very good in the US compared to elsewhere.

Many of our poor health outcomes seem to be due to lifestyle issues (obesity, drugs, lack of exercise, etc) not our actual health care system.

Not disagreeing with your comment as I think you are mostly right. Just thought you might find this interesting.
