I guess they've thought all this through, but on the face of it it looks like "Westerners really love pop groups doing choreography in designer clothes. For some reason they forgot how to do this themselves so we'll step in!" And that's not it. K-Pop has
- the Korea fetishists
- the more specialized "this particular group of Koreans only are special, the others are ugly losers" tokeners
- the "not like other girls" girls who think K-Pop is superior because it's in a language they don't speak
- the puritans who really believe in 28 year old popstar virgins who sit in the dorm every single night gaming with their members
- the individuals who get some complex inner need met by crying over the perceived suffering of their faves
The west can't tick these boxes.
