Significance of 'mixed' performers, immigrants and 'second gen' in this?

When Yang gives Wade the invitation at the beginning of this, he mentions the party is a networking event for "second generation" types. Jerry Huang, the actor who plays the evil Yang, is obviously Eurasian, despite his repeated claims in the media of being 100% Taiwanese (technically true, as he was fully raised there, but his true parentage is actually mixed). The heroine of the film, played by Julianne, is named Hitomi, who I believe is also supposed to be an import to the island, as is Vivi Ho's character. The triad-turned legislature member and the piano player seem to be home grown, as does the hero Wade. Then there's the OTHER villain, a euro-trashy, soul-patched American expatriate played by Kristian Brodie. The movie's argument is that the rich are sick of the poor resenting them and the trying to take from them, so they kill the poor (the working poor, in this case) at these annual shindigs to vent their frustration, but it's interesting (or is it?) that the ringleaders of this little escapade are shown to be something other than "pure" Chinese (though many of the elite in their audience appear to be - could that be a suggestion that only the "outsiders" have the balls to do what the "insiders" wish they could've done all along?).

Regardless, the movie's BASIC talking points are simple enough for 18 year olds, though I'm curious if there's some kind of "second gen" syndrome within Taiwan culture, since it's very obviously referenced in the film. Frankly, a more pointed "message" would have been to have them doing it JUST for kicks, without the awkward justification ("We despise the poor. So we kill them. Because we CAN! Bwah-hahahahah!). Considering the logistics of the event itself are just sloppy enough to allow two new recruits (out of five) to gradually worm their way out of the gruesome proceedings suggests that the rich villains haven't quite learned the value of installing adequate controls, as this is the FOURTH event they've held and people are still able to turn the tables! (remember, this isn't supposed to be a HUNT; it's supposed to be a straight-up torture show, but they obviously never thought to keep their victims on short leashes, or check them for GUNS at the door! LOL)

Good movie. Not a great one, but it's up to the standards of HOSTEL, SAW, WOLF CREEK, THE LOVED ONES and other "torture" horrors in providing cheap thrills and gross-outs for the 18-year-old set.

I'm just curious if the high number of mixed-race, immigrant and expatriate characters is some kind of statement unto itself.
