I have several friends who work for a West Coast health care system, in three different facilities, and one who deals with them from the outside (insurance). They are in 5 states, they have 30 hospitals, 250 clinics, and more than 1,600 physicians. They are also one of the most FU'd businesses on the planet. Worse, they are probably just average in the industry.
When you go to a doctor, they have been instructed to give prescriptions for the newest, most expensive meds, when the older and cheaper meds would do just fine.
Big Pharma takes govt grants from our taxes to create new drugs for which they charge a fortune -- well, in this country, anyway; the same drugs sell for much less in other countries, as you know if you've been to Los Algodones.
The industry has been made so complicated that it costs a fortune, and if you don't insist on getting an itemized bill (and scrutinizing it closely), you're very likely to be paying for things that you shouldn't be.
Eight out of ten hospital bills have errors, some of them in the 5-figure range. And if you bother to check it, you will likely find that you have been charged for all kinds of things that weren't used, you didn't get, that you didn't need, and were double-charged for. Heart attack patients are charged for baby bassinettes. Dead people are charged for room occupation for two days after they died. Appendectomy patients have their intestine accidentally knicked with a scalpel by the doctor, and the patient is charged for repair costs of the damage. Have a heart attack, and they may charge you about $15,000 for "medical supplies" when you're in Intensive Care, which consisted of oxygen, a ventilator, cardiac monitoring, etc; but these are ALREADY included in the cost of being in the Intensive Care Unit (ICU). Some medical supplies (like pacemakers) have warranties -- if a part has to be replaced, they shouldn't be charging you $35,000 for replacing a part.
My brother recently had triple bypass surgery. By the fourth day, he was still having problems breathing, and the doctors were concerned. They decided to send him home with an oxygen machine and oxygen tanks (for power outages). He blew his nose on the fifth day, and felt a lump in one nostril, so he worked it out -- 'it' being a large blood clot from the tube they stuck in it. The doctor came in for the daily exam, looked at his history, and said, "You've been having trouble breathing since the surgery, but you don't seem to be having any problem now". My brother handed him the tissue with the clot in it. It had never occurred to anyone to check his nose.
All of this crap, multipled millions of times, costs a huge fortune. You pay for it out of your own pocket, through the rapidly-increasing insurance costs, or via your taxes. There are no free lunches in health care, but we shouldn't be paying for stupidity, mistakes and outright theft.
