I was recommending relying on market forces. Which I'm reliably informed is the only way to achieve the correct result. I'm shocked to find out the invisible hand of the market is not the perfect and reliable process I've been told it is.
This is gonna ramble....
Part of the problem with the "market" in regard to US healthcare is that the system is pretty adulterated to the point that the market doesn't really work the way we think it should. I think I read somewhere that when insurance was first introduced, the AMA opposed it for this reason, saying it would drive costs up. I think it's worth noting, however, that medicine was more primitive at that time. Hospitals mostly consisted of room and bed space. There were not expensive pieces of equipment like MRIs or the types of lab and imaging services we have today. Or the surgical equipment.
Insurance, by its nature, separates the demand for the product from the supplier. How many in the US even know what the fee is for a doctor's appointment. (One time, I asked at the front desk how much the appointment would cost without my insurance. Nobody in the office knew.)
Also, generally speaking, cost is not a topic during the appointment. The doctor says: "We need to do these tests." or "It looks like you have X condition. We can try these treatment options." There may be discussion of the advantages and disadvantages of the options, but it usually doesn't involve laying out the prices. (Your doctor may say something like "This is the best option, but the insurance company will make us try these options first."
Price negotiation happens between the providers and the insurance companies. the insurance companies can pass the price through to patients in the form of premiums. Patients (or employers) shop insurance based on the premiums they can afford more than the fine print of coverage limits.
Whenever there's a story about unaffordable healthcare, it always seems to be about insurance premiums or inability to afford insurance. (Evil insurance companies.) Then there are the stories about how Medicare doesn't pay enough so doctor's offices are limiting the number of Medicare patients or declining Medicare patients entirely so the elderly can't find a provider. (Evil Medicare: Reimbursement rates are too low.) Stories about salaries for Healthcare providers are almost always: "Nurses are underpaid and overworked!" (Evil Hospital administrators.) It's never about how much doctors make. The salary of the CEO may be questioned, but not that of the doctors (even the administrative ones).
We want cheap affordable healthcare where the healthcare providers are well paid and the provider to client ratio is high. (You can substitute "childcare" in that sentence as well. Either one is a bit of a paradox.)
I'm lucky. I've had a "Cadillac" plan pretty much the whole time since I graduated college. It's an HMO. My part of the premium (Family plan) is like $250/month. My employer pays about $1000/month, I think. No deductible. Copay for Doctor's visits $30 Copay for hospital/ER $300 per admission. After reaching the out-of-pocket maximum (It's happened) the copays go to $0.
I kept my daughter on my plan until she was 26. (Thanks Obama!) Even after she was married. When she was pregnant, the insurance would pay for her, but not my grandson was not eligible as he is not my dependent. Her husbands insurance had lapsed due to a period of seasonal unemployment six months earlier and there was a two month gap before it would kick back in. (He's in the trades...the union insurance coverage is tied to on the number of days you work in the previous quarter or something. It's complicated.) So I bought the same plan for my grandson for two months at $500/month. (Left the hospital with no bills, though.) The person at the insurance company, by the way, was very helpful, and the process was very smooth even though I was up front that I was only keeping the insurance until my son-in-law's kicked in and charges would likely exceed the premiums by $15,000. (Not everyone is evil.)
My wife was in the hospital for a couple weeks last summer. Our copay was $300. (Well, actually $0 because she also has Medicare as a secondary payer.) The charges were around $150,000. I think that one incident accounts for about ten years of premiums. Just to give an idea of the math here.
The interesting thing is that the insurance company, the main hospital in the area and the "physicians' group" are all part of the same overall company. The Hospital portion is "non-profit" but the other parts are not. (Not sure exactly how that works.) (Our plan, by the way, is better than the one the employees of the company get.)
Health insurance (private or single payer government) depends on healthy people's premiums subsidizing the expenses of the people who are less healthy. If the young and healthy opt out, then premiums go up. If providers waive charges for those who can't pay (or are never able to collect...same result) prices go up and premiums go up.
My impression that in many of the countries with universal healthcare the doctors are employees of a national provider service. So taxes go to provide the facilities and staff. If taxes (premiums) are too low, patients have to wait for care, newer treatments are not available and/or doctors/nurses leave for more lucrative opportunities (private or overseas). If you raise them...well, no voter like higher taxes. But these systems have an advantage in that the expenses can be centrally managed and there is 100% participation. (Of course, low-income people still don't pull their weight.)
