We live overseas in Hungary without insurance and are fine. Even factoring in major expenses like surgeries and emergencies it costs less than the Medicare Part B payment I am required to pay to keep our awful and useless Tricare Overseas plan provided to retired military ex-pats. We have had emergency medical problems in non-EU countries such as my wife fell and broke both her tibia and fibula in 4 places requiring major surgery and a week's stay at a hospital in Sarajevo. That cost us 1,000 Euros and compared with similar surgery in the US roughly 1% of the cost with no other payments and VIP treatment (private room). The surgery a year later to remove the plates and screws was under $400.
This year I crashed riding my mountain bike and it looked like I fractured my femur so was carted off to the hospital by ambulance, treated, x-rayed, etc. and released within 2 hours at a cost of roughly $300. I was lucky as it was "only" a massive contusion. I did actually have 2 broken ribs, a broken clavicle, and 2 broken fingers which they found and I didn't know about and were treated at the same time. I also got a tetanus shot as well as COVID test in the process. No long-term sequelae.
My wife again had major surgery for emergency gall bladder removal and again went by ambulance, got an ultrasound, CT scan, lab work and all surgery etc. That was a bit more expensive as it became complicated and she had clinical death in the OR requiring resuscitation and intubation. She had a very large area of inflammation (necrosis) requiring the removal of the duct as well and part of her liver. That all came to roughly $3,000 and again VIP treatment. She is in excellent condition now and only complains about the 4 scars. I will comment again about statins causing gall stones and this was her problem. Was it caused by her taking statins? Who knows?
Anyway, my point is that in the US you all have been like boiled frogs with very slow warming of the pot until it is so hot you aren't even aware how awful things are in the US compared to everywhere else. Americans just accept these ridiculous prices as "normal". You can get excellent and cheap care in all other countries often for free.
