Why just Canada and the UK? Germany, France, Denmark, Sweden, Norway, etc. etc. also have so-called Universal Healthcare.

It would be easier to list developed nations that do NOT have it.

In addition to asking how people like it...you should ask how well does it work. If Canada and UK deny medical care to the elderly - you would expect to see shorter life expectancy. The US is 24th in life expectancy - compared to UK at 14th and Canada at 12th.

In overall measurement of the quality of healthcare (infant mortality, etc.) the US ranks 37th.

Yet the only country that spends more on healthcare as a percent of Gross Domestic Product (GDP) is the Marshall Islands.
