^actually the numbers show the average person is better off as far as I have read. Wealth and income are disproportionately being accumulated by the elite but Canada is one of the few countries in the developed world where middle-class people are still doing (marginally) better year over year.
Regarding resources one of the things Canada has is economic potential. In a way we aren't a developed nation, we are a developing nation. Canada has this big backyard called Canada, a notable chunk of the world's surface area that is essentially un-populated and un-developed. We haven't even realized the economic potential of the near north let alone the far north. I'm not saying it is right or possible (due to the hostile environmental conditions) to exploit this area but the fact is we are generations from doing so. There is a lot of work ahead. The Alberta Tar sands, Gas shales of British Columbia, and Ring of Fire in Ontario are examples of near north resource areas. This is the near north remember we are talking about not the North or far North.
Even in terms of infrastructure you can really see how Canada is not developed, we are developing. "Developing" countries like China are already surpassing us in infrastructure build-out. We have skeleton rail, highway, bridge, port, pipeline, material processing, urban transit, etc. systems. We could easily be building this kind of infrastructure if we weren't spending it all on health and education (vital sectors in their own right but syphoning all the money from productivity enhancing developments).
