I would describe Canada as generally being tightly range bound. One of the most striking things about coming to the U.S. is the large class of what I would consider to be the working poor. People who are truly just doing enough to get by and are one mishap away from financial ruin. Of course, having lived in SF and NYC this is constantly juxtaposed with extreme, incomprehensible wealth that is equally striking.
In Canada, in my experience, the vast majority are still in the middle with few outliers in either direction. Earning potentials are significantly capped - even in areas like banking and tech - and social programs make it quite difficult for there to be the kind of working poor I observe daily here.
I've often thought to myself that I couldn't imagine what it would be like to make $50k in the United States (even living in a low CoL area). From health insurance, to private school costs (given the quality of many public schools), to college costs. It would seem an intense burden. Certainly if I had offers that paid between $50-100k in both the U.S. and Canada I would move back to Canada. I would feel I have no other choice.
With all that said, I make many multiples - especially after tax - of what I could ever have hoped to make in Canada. I have been inside institutions with the kind of institutional framework with no comparable in Canada (from a human capital and technological perspective). Opportunities have been afforded to me here that either do not exist or are analogous, but significantly inferior in Canada. The United States has given me a wonderful life and I'll always be grateful for the opportunity to be here.
I make no claim as to which economic system is better. I would just observe that Canada is a much easier place to live, but in my experience lacking in the kind of dynamism you see in the United States (that translates into personal opportunities, income, and fulfilment).
[1] Top is obviously somewhat subjective. McGill, U of T, UBC, and U of Waterloo would be the "top" schools. The "top" jobs are FANG or FANG-adjacent, investment banks or hedge funds (GS, JPM, Citadel, etc.), and consulting firms (McKinsey, BCG, Bain).
