Other nations have a variety of strategies. There is no particular consistency between them (e.g. compare Israel, Switzerland, and Canada’s universal coverage systems), so while we could randomly pick one and go with it, I think it’s better to understand why our costs are so high compared to everyone else (roughly double the average of other modern nations).
That I’ve been able to determine the historic tendril of the US’s problem is our attempt to use employment as our way to push most of the population into gaining health coverage. Tax incentives were offered to the population to receive plans through their employer, and so employers started to offer plans.
In other nations, there’s a cost to health coverage. If the government is footing your health, then they’re going to have their financiers running cost-benefit analysis on available treatments and only approve those which make financial sense. If you’re an individual buying insurance from an insurance agency, you’re going to want the cheapest possible option, which pushes the insurance agencies to offer low-cost but still acceptable options. So, again, they’ll do some research to try and make sure that the cost-benefit of various treatments are worth it.
But when my employer offers me an insurance plan, his goal is to entice me to come work for him. Ultimately, the money that goes into the plan comes from my wage, but people tend not to look at it that way. They just look at whether company A offers more than company B, without much taking into account whether the plan actually makes sense from a Expected Years of Life Gained vs. Cost perspective. This has meant, in the US, that we have the most high-tech treatment options of the whole world and the prettiest hospitals (with TVs in every room, etc.) but no significant improvement on our life span. The simple truth is that most of our high-tech MRI scanners, laser cutters, and blue-tooth dental xray systems just aren’t as cost effective as plain old asking where it hurts, metal scalpels, or old-fashioned xray film.
In countries where people go to an insurance company, rather than where health coverage is entirely controlled by the government, health spending still tends to be higher. Obviously, it’s in those companies’ interest to try and upsell you. They don’t care as much whether the plans are worth their cost, just whether they can sell you on it. But I still prefer private insurance because it allows one to choose their own plan, and different companies are going to experiment with different treatments, which is useful for making sure that new technologies are properly trialled. Plus not-gubmint. So having plans be reviewed by an independent party, and that information made public, seems like a way to gain something like the reduced cost of government coverage, while still keeping the benefits of private coverage.
One thing that I fear, if the US took on the Canadian or UK model is that, at the moment, the US is really the only country buying and using the most modern medical technology. It might not be cost-effective, but buying today’s medical advances help to fund tomorrow’s medical advances - which will eventually become cost effective. I don’t want to shut down the only source of income for advanced medicine, outside of abstract scientific research, that currently exists in the world.
I am also worried about making a dramatic shift. If you declare “All health coverage is under government mandate!”, then you’re effectively putting large swathes of the insurance industry out of business. I’m not sure how many people would actually be effected, but I still imagine that it would result in a fairly large number of layoffs across the country. Given as we’re already on private care, it seems smoothest to continue that, for the economy.
