Last time I checked, Australia had better cancer survival rates than the US, higher quality of life, greater expected life span, and a hybrid medicare / private insurance system that covered almost the entire population such that very few faced medical bills outside the reach of their income (or lack thereof).
I had a stent inserted to clear a clot that travelled to my heart from a knee injury - free (surgery, two and half days in hospital, follow up recovery and lifestyle advice appoints).
The ambulance cost more as I was between St John's Ambulance covers at the time, that was $500 which I was happy to pay (myself, my father, and multiple family members have all worked as volunteer ambulance drivers and paramedics over the years).
