What I mean is:

Asian Chinese in real life-->Becomes white anglo-saxons that observe same cultural norms as Asian Chinese

All White Americans -->Becomes South Korean Asians but observe the same American exceptionalism and sense of entitlements that White/Black/Latino Americans exude

Mexican Latinos-->Become South Koreans

Japanese-->Become Icelandic

In the show or movie, every race and nationality as been swapped with one another

Then you tell the story the same way you would if none of the races had been changed.
