Disagree. I had a valve replaced, and researched extensively what my experience was like vs. that in other countries. I received an unquestionably higher standard of care. I had my choice of valve, doctor, hospital, I had nearly zero wait (a few weeks from diagnosis to surgery, and only because I asked for the time -- in my circumstance there was a double digit chance of death, and I needed to ... process), and the nursing care that I received after surgery in the ICU was literally one-on-one - there was a nurse assigned to
me. I had a bed that massaged and hammered the goop out of my lungs, I had tasty food (when I could eat again), and I had some say in when I would be discharged. The only thing that wasn't absolutely first-class was that I had a shared room with two beds post-ICU, but even that's becoming uncommon in the US.
After reading on the experiences of people from European countries and Canada in the 'OMG I had a valve replaced' forum (yes, there's a site just for that -- valvereplacement.org), the level of care that I received was significantly better than what is typical of public health systems.
Oh, and last week I needed to see the doc for a sore throat, and I was in the same day. Queues are a regular thing in public systems.
