I think the biggest driver of high medical costs in the US is overutilization of services by the insured. It’s similar in concept to taking your car to the mechanic and saying “do whatever you think needs doing, the more you do the more money you make, and I’m not paying for it so I want everything possible done.”
Medicare had a study of two areas of the country one around Dallas and one in Oregon. The costs per enrollee were twice as high in Dallas because there were so many more doctors. Supply creating its own demand.
So I think putting poor people who are paying nothing into the system into such a system would simply bankrupt the country even faster.
The people currently getting the gold plated, spare no expense care, have no reason to want to change. Anecdote, my friends’ daughter hit her head. Didn’t pass out but did feel tired later. They insisted on a cat-scan ordered and why not? It’s not their money. Repeat millions of times and you have our predicament. Cancer which killed surely and cheaply 30 years ago is now “curable” or at least “treatable” but only at great, great expense. This is a good thing, but it’s expensive too.
The problem is not in the profits of “insurers” or “getting the government to ‘compete’ with them”, or even in pharmaceutical prices. Pharmaceutical companies create drugs and as far as I know, it’s illegal for medicare not to pay for a drug just because it “costs too much”. Brilliant. So if a drug can extend a 95 year old’s life 3 months at $100K per month? Yep, they pay it. It’s untenable.
Back to the OP, I wouldn’t mind paying for “basic” care…broken arms, pre-natal, immunizations, chronic conditions maintenance for poor people. Even expensive treatment on otherwise healthy people if it will do some actual good.
It’s the gold plated care I don’t want to pay. The cancer, heart bypass operations, expensive surgeries on elderly people…“but wait, does that mean you’d just let them die?”. Unfortunately yes. Don’t have enough money for everything, sorry. The UHC in the UK have to make choices like that, as far as I know. They have a budget and have to stick with it. There isn’t an infinite amount of money and needs will grow and grow as technology advances.
As for insurance being unavailable for pre-existing conditions, maybe high risk pools could be subsidized by the gov’t. I don’t have any easy solutions to that. It’s not realistic to expect the insurance companies to take on very sick people for the same rate as healthy people. Adverse selection means the policies will be very, very expensive.
As to the other “the UK has a higher life expectancy”. I think it’s a canard. Life expectancy isn’t a good measurement. Does the UK have unlimited guns like we do? Crime? Rampant obesity? Drunk driving? Give me the life expectancy of a person in the UK with stage 3 breast cancer vs. a person in the US (with insurance). That would be relevent.
One way I’ve heard it phrased is “what give you (the person with insurance) the right to have better medical care than some poor person?”. My answer is that if you pay for something, it’s yours. If you have to get something through moral or government coercion, it’s not the same. If you have the money you should be able to spend it (through insurance) on great medical care if you want it. There’s no reason the poor should expect the same medical care just as they shouldn’t expect the same house, car or university for their kids. That’s just the way I see it.
