Uhh Chinese demographics and econonomics [sic] are sort of a common topic in America...
No, they are not.
Well not for ignorant Japs apparently*. But they are common topics in American and Japanese halls of power.
You're on a US political message board. It's probably safe to say most of us have been exposed. Here is an example of the litany of content produced constantly in American think tanks
Council on Foreign Relations
Hudson Institute
BakerInstitute
Center for a New American Security (CNAS)
There are hundreds of hours right there and it's just 4 think tanks lol, it's searches in their youtube for the word china. You'll see endless hour long panels on any topic you'd like.
Should be common knowledge to anyone who frequents a forum like this
