Logically this may make sense, but in reality it does not. Other countries with more sane healthcare systems have costs that are fractional compared to ours despite having the exact same costs you mention.
If the equipment is the same, the admin overhead is the same and the education is the same, then that leaves only one real difference between us and other countries. And that's our Byzantine insurance system.
Costs, regulatory overhead, education and taxes are different everywhere.
My wife pays tens of thousands of dollars per year in malpractice insurance...and she isn't even at the top of the scale in terms of these costs. The cost of education? An MD can graduate with anywhere from $300K and more in debt.
And lawsuits? Show me a place on earth where attorneys will go after anyone, medical industry or not, as quickly, easily and violently as they do in the US?
Show me a place on earth where the government guarantees student loans to the extent that university costs are bloated to the point of creating financial slavery for graduates.
Show me a place on earth where doctors have to order a pile of unnecessary tests in order to protect themselves from being sued.
Show me a place on earth where developing the simplest medical device costs tens of millions of dollars in regulatory fees alone (if you are lucky).
Show me a place on earth where bringing a drug to market comes with potentially billions of dollars in regulatory costs.
Show me a place on earth where a manufacturer of N95 masks and gowns is not allowed to supply them to hospitals during an emergency due to regulatory burdens, the fear of lawsuits and has to demand immunity from the president of the country before they are able to do so.
I tried to develop a relatively simple hearing device to help people who suffer from SSD (Single Side Deafness). We have someone in the family with this condition. I designed and built a device for her. She loved it. I then looked into going to market with it. The costs would run into the tens of millions of dollars (or more). There was no way to take that leap. And that doesn't include protecting from or fighting the inevitable lawsuits.
No, nothing is "the exact same". And that's my point. Unless you pull-up a spreadsheet and analyze the cost structure you will never understand why healthcare costs what it does in the US. It has nothing to do with insurance, or profit, or greed or any of the nonsense ideas being floated around --particularly by politicians who just want to manipulate the audience for votes.
This is a simple equation: If you want to lower consumer costs you have to lower the cost structure driving the process and resources necessary to deliver the goods and services they receive.
I would urge you not to form opinions as you have until and unless you have taken the time to truly understand the details of the matter, which is to say: Analyze the cost structure tree down to a good level of granularity and then see what you would change in order to reduce consumer costs. Insurance will not be on that list.
If the equipment is the same, the admin overhead is the same and the education is the same, then that leaves only one real difference between us and other countries. And that's our Byzantine insurance system.
