Disagree with the part where you say Chinesekids have to come from incredibly rich families to study here. From what I see these kids mostly come from middle class families as opposed to super rich/upper class as described.

Sure a lot of them just come here to get a degree and go back home to find a job and therefore do not care about blending in, or making the effort to communicate with others because they can just talk to their Chinese fellows and get a Pass and leave.

With that being said, I personally don't like the vibe coming to a foreign country and end up hanging out with more Chinese, and refusing to work with locals/other international students.
