America is fundamentally an Anglo-Saxon, majority European project, it seems to me, and that's not a bad thing.
Consider the others in that class:
United Kingdom, USA, Canada, Australia, New Zealand. Am I missing any of note? The USA has more in common with that category than other immigrant-defined nations like Brazil or, well, Brazil, it seems to me.
The dull truth is we're another English-speaking, mostly white nation, and they're all doing pretty good. In some respects almost as well as Scandinavian nations, in fact.
