Quite a stretch to jump to "everyone might be miserable". Immigration from Latin American and other non-anglo countries is on a scale where it shapes American and British domestic politics, difficult to conclude that those immigrants are searching for the misery of anglo cultures that they can't find at home.
I think you're trying too hard to muddy the waters by creating a definition for "anglo" that does not match reality or any use of the term.

Even within "European Americans", nearly half has an ethnic origin that is classified as German, not English.
Another important aspect is immigration and naturalization. The bulk of high-skilled R&D specialists who turned the US into the technological powerhouse that it is aren't exactly Mayflower descendants. It's immigrants and first- and second-generation. So it's very hard to argue about "Anglo" thins with the extreme reliance on immigration and descendent of immigrants to play the roles that made all this progress possible.
- German and other NW European cultures share the family atomization characteristic of Anglo-Americans
- Anglo as a term stems from England. England is named for the Angles, a Scandinavian/Germanic tribe that invaded Britain a long time ago. The term Anglo-American reflects the seminal English influence on American culture.
- The English and their descendant culture, America, basically invented the modern economic world and it predates WWII by a long time.
The idea that WWII is why America is on top is a-historical.
How so?
I'm actually here to point out that the U.S. had the world's largest GDP as early as 1890, or as late as 1913, depending on your source of data and how it's estimated. So, WWII isn't the origin of that. We can now argue about whether GDP is a good indicator, but before doing that I'd ask for a better one (with historical data) to be suggested.

Aren't Scandinavian people statistically the happiest? That's not anglo culture.
Different cultures also define happiness differently. For the scandanvians, happiness stems from contentment and balance, American society tends to link it to consumerism and material success.
It was a huge country with lots of natural resources like oil, gold, coal, etc.
That line of reasoning is just plain sad. It boils down to "everyone might be miserable, but someone else is getting rich so it's good."
What makes it specially sad is how anglo culture's economic advantage spawns from the outcome of WW2, not this misplaced sense of sacrifice.
