What comes to mind is the stories about "parachute kids" with (relatively) wealthy parents that sent the kid abroad, ostensibly for study. They end up in an extreme form of latchkey existence - still Eastern in intent, but living largely alone and with few obligations, they tend to be adrift at a much earlier stage of life, leading to occasional news stories about crimes that earn prison time, or of "little emperors and empresses" that have been spoiled and have difficulty adjusting to interaction with the rest of the world. The film "Better Luck Tomorrow" explored this - not specifically the parachute kid status, but the trouble that overprivileged Asian teens get into. It's fictionalized but also based on some real events.
