Not just greed. But it reeks of being completely disconnected from the society/surroundings you inhabit and having a complete inability to read the room. The fact that they think Eileen will come back and go to Stanford and everything will be fine and dandy is complete and utter delusion.
No one is stopping her from making her choices. But people are allowed to feel a certain way. The fact is the mom has a complete inability to read the room and this is because she is completely disconnected from American society. Her interactions with Americans are probably limited to talking to and paying contractors/vendors to do repairs for her on her properties or to instructors who are training Eileen in whatever class she is enrolled in.
1, According to China's nationality law, Chinese children born abroad can have two passports before the age of 18, but they must give up one after the age of 18. In other words, adult Chinese are not allowed to have dual nationality, and overseas Chinese under the age of 18 can not make a choice for the time being.
2, Gu Ailing's mother and father are high-end elites. Her mother works on Wall Street with a high income and a broad social circle, her mother is definitely not what you call a closed Chinese woman. Gu Ailing has always received top education, Gu Ailing has studied equestrian, skiing, golf, tennis, fencing and so on.
3, I admit that her mother has long made arrangements for Gu Ailing's country. According to China's entry records, Gu Ailing has lived in Beijing for nearly 100 days every summer since she was 5 years old. She has a huge social circle in Beijing, and she can speak fluent Beijing dialect. Before she gave up her U.S. citizenship at the age of 16 (U.S. law does not allow children under the age of 15 to give up their U.S. citizenship), she had lived in her residence in Beijing for 11 years. Gu Ailing's mother even let Gu ailing receive primary education in China, which makes her have Chinese people learning habits. Of course, she also has a long time to train and study in USA every year.
4, I admit that I underestimated the anger of Americans over this matter, but Gu ailing doesn't have only one choice. She can still go to European universities for study and training, and Beijing is not a suitable place for winter sports.
Gu Ailing's mother has a high income. Gu Ailing has a rich family. She likes a variety of sports, not just skiing.
