But think about why the U.S. can't make health care effective in order to get more health out of less money: is it the left wing or the right wing that is against?
Realistically, both.
The US has a large for-profit delivery system - hospitals, doctors, medical device purveyors, medical supply companies, etc. They all want to profit off of the system, and the mark-ups are absurd. The acetaminophen that costs less than a dime per pill over the counter is given to patients for a charge of $15 (or more) per pill. It's not a different medicine, and it doesn't cost the hospital more to acquire. They purchase in bulk at a discount, and mark it up to make money off of the patient, and more importantly the patient's insurance company which has no ability to deny a 15,000% inflationary charge. And that's barely the tip of the iceberg. The amount of venture capital involved in hospital and physician systems is abhorrent, it's literally funding the ever increasing cost of care delivery in the US so that investors can make mind-boggling profits off of a necessary system.
The US also has a large insurance system, about half of which is for-profit. That insurance spreads the delivery costs around to everyone, passing the investor's profit off to everyone in the form of increased premiums. And I know, I know, most of you think insurance is evil, but the amount of profits that insurers are allowed to make by law is tightly monitored.
Between those two, it's tens of millions of people employed. Just the health insurance industry has over 700,000 direct employees, with about the same number in secondary support and contracted employment. A massive overhaul of the system will absolutely disrupt the economy of the US and cause widespread unemployment.
And don't forget the impact of medical lobbies in the US. They've got the ears (and pockets) of politicians of all parties.
At the end of the day, both wings are against creating massive unemployment and losing their grift.
