The problem with our health insurance system is that it's insidious. Our doctors spend ~25% of their time filling out information that only gets filled out to try to get insurance to not deny the claims, and hospitals have entire billing departments whose only job is dealing with the billing of our stupid ass system. The problem isn't just the ~15% that the insurance companies take directly, it's that since their percentage of profit is capped, they work to raise prices of the entire health care system so that their 15% cut is bigger. Insurance companies literally negotiate pharma companies to charge a larger amount to uninsured people so they get to take a bigger cut.
That's not all of the reason (some of it is higher cost of living, compare G20 vs G7 and the gap narrows a bunch). Some of the reason is because of US education costs, and immigration policies that make it harder for people to come and work in healthcare.
Does it? Average physician cash comp in Germany is 75kEU, and average cash comp in the US is something like $350kUSD. Note here I'm using one of the largest and soundest economies as a comparison, and one with substantial uptake of private health insurance.
If what I was backing with "pie charts" was "everyone else is being unreasonable", sure, but that's not what I said. Go look it up. Zero out all insurer costs. What percentage of health care costs do we save?
There's a lot more than just "Insurer costs" and "Doctors' BMW payments" in the pie chart. Again, relatively little of it has to do with actually treating injuries and illnesses. And that's not even getting into the massive market distortions associated with forcing the concept of "insurance" into a market where virtually every single customer will eventually need to file multiple claims.
You usually come up with better arguments than this. We all have off days, I guess.
I've lost track of what you're saying. I'm saying that if you zero out the insurance companies, you don't significantly impact total health costs, because the insurers aren't where those costs are; that's the claim I made upthread you found "... novel", but it's not novel, and it's easy to go verify.
