Not to get "political", but when DW/me were down under a couple of years ago, the health system (defined by our guide) was a bit "wanting", as far as the basic system (e.g. beds in the hallway) vs. a private room for those that could pay for a supplemental plan.
That's much different than say the "Canada System" which does not allow supplemental insurance, and in some cases drives those near the border to cross over (and pay) for USA doctors, if they did not want to go "on the list" for months - or longer.
I guess the question does come up - regardless of health coverage under a national system, of retirement income. In this case, the "super annuitunt" vs. the SS system we have in the States.
My simple observation (as one who has w*rked and traveled in many, many countries) that there is no "best" system - both in health, and retirement income.
BTW, I did w*rk for, and in Sweden - which is shown as an example (in a lot of cases) as the "perfect system".
As for me? I could not survive (with my goals) in that system. Rather than give an advantage to those that strived, they tried to reduce (through excessive - IMHO - taxation) a level where "most are equal".
Sorry, I have higher goals.
I guess we (as humans) will never agree to what is "best", for all (but again, that's just what human is being all about)...
