I believe that Kpop is only for Asian people, as it has the name Korean pop. I will take a real-life example of Eric Nam because he was born in the US and wanted to pursue music but because he was Asian in the US he was denied many opportunities to be a musician.
He went to pursue music in Korea because even though he did not speak Korean there would be more opportunities for him there than in the US.
In Korea, Eric faced his fair share of discrimination for not being "fully Korean" (even though his parents were both Korean) however he still had more opportunities in the US.
Now that he had built up a strong fan base, he has started singing in English which is what he wanted to do, to begin with.
Kpop gives representation to Asian musicians, where "western" musicians already have a music industry rather than going into Kpop
But this is just my opinion and I look forward to reading everyone else's
