There are a few 'illusions' out there that people live by.
One good example is the 'Western' version of the End of the World. It was a basis for their leaving Europe (End of the World) and going to Namerica "The New World" and savior.
North America (The West) is, via the International Dateline - basically the 'End of the World' and thus it plays a huge part on their cultural psyche.
Also - Namericans are very 'sky/heaven' based. You could say they are the 'Avians' of the Planet and their successes in Wars have been due largely to their 'Aviation' input.
That's why you also hear of many Namericans going on about seeing 'Lights in the Sky'.
So you have both the End of the World (now they want to escape to Mars) and everything in the skies/heavens.
As they are a 'New World' like Oceania, Sahul and Samerica - their 'mascot' is the ALIEN with its huge brain, but runty body.
It's the opposite of the Old Worlds (M-E, Europe, Asia, Africa) and their 'mascot' - the 'Cave Man' with his physically strong body, but pea-brain.
In the Old Worlds - they strive against being like the Cave Man.
But in the New Worlds where life is physically easy due to machines doing the work for you, but mentally more complex and hard... people in the know

strive for better health rather than knowledge.
That's why you have so many 'Mental Health' issues in the New Worlds.
Old Worlds: Life is physically harder, but mentally simpler.
New Worlds: Life is physically easier, but mentally complex.
So you ran from the past, but now you know you must not rush to hasty into the future.

Btw - Australia does have a substantial population of people who live the Namerican mythology of all things in the sky (like ScoMo and his NASA hand-out of million$) - but a lot of Australians live beyond just the 'Down Under' tag and dive deep below the oceans to find the Light Within.
