And then you realize that the population of Canada is 10% of US. Canada should be compared to the Nordic countries vs. US in terms of quality of life etc.
It's not that simple, really. Although for some comparisons you are probably correct, in other ways they are a very natural pairing. For all their differences, in many other ways Canada and the USA are much more like each other than either are like any other country.
While we might be a percentage of the overall US population, we are fortunate to have access to most of the same things as the USA, just with a few extra nice things like health care.
