Conflating capitalism or nationalism with human nature is a typical display of internalization of naturalised settler-colonial rationalities. "Greed" is a conveniently vague explanation for someone who cannot or will not imagine a world without this system.

Canada is a settler colony. Its only purpose is to facilitate the extraction of resources within its borders to the greatest effect under capitalist imperatives of infinite growth and profit maximization. When I say it isn't a nation, that isn't because I think nationalism is any real way to imagine human organizing, I say it because Canadians cling to an idea of national identity to justify what is fundamentally a brutal, inhuman system.
