I think this is certainly true, but at the same time, I've never met an American (even an otherwise 'uneducated' one), who was under the impression that London or Berlin are backwoods villages that struggle to keep the lights on, whereas I have certainly met people that think Hong Kong is. So then the question becomes "yes people are generally unaware, but what is it about Asia specifically that makes it seem like there is an even larger lack of awareness compared to somewhere like Europe?"
In regards to the rest of your comment: I wholeheartedly agree, but I don't think it comes down to "time or resources". Some of it does just come down to personal habits/preferences. Without passing any judgement, there are plenty of people who spend their evenings watching The Bachelorette when they could just as easily be using that time to watch The Travel Channel (or Discovery Channel if it was still actually educational), but they actively choose not to. I think that's a societal thing much more than it is a time or resources constraint.
As for the asymmetry. The US has been considered one of two, then the only, global superpower for the last 70 years, inundating the whole world with their culture the whole time.
Reminds me of a course on models, where they talked about "celebrities". Those who are seen by and influence most people, but don't know and aren't influenced by most of said people (might need to clarify that)
The most investment-worthy economies on the planet have been in Asia for the past couple centuries (if you understand buying the dip), this fact is an economic threat to Europeans with a zero-sum view of global capitalism (has been for at least 2 centuries). The rest writes itself....
