US here. I know the q is not for me, but I’ll answer anyway!
It’s not the quality of the health care that concerns me, but the availability, or lack thereof, due to insurance and pharmaceutical costs.
I think that as a far as medical technology, the US is on a par with any other place you’d like to name.
That being said, I’d like to see the availability widened. As a person over 65, my Medicare premium is a little over $100 per month. Payment of that premium entities me to the full spectrum of medical benefits through my choice of several insurance companies offering a version of “Medicare Plus”, including such things as $10 copay for primary care, small or 0 copay for prescriptions, and free access to fitness programs with personal trainers available. I would very much like to see such a program for all US residents.
