Chinese kids would learn better English if they were dumped on the streets and left to fend for themselves than if they were enrolled in a US university.
English majors can't read English so the idea the same colleges would be able to teach Ching Chong Ding Dong is retarded. If wealthy Chinese are trying to anchor their kids it's because they want to escape the CCP. Some are plants, but the majority are self-interested, same as most immigrants that want to to come to the US. Asians (at least Japanese, Chinese, and South Korean) are better immigrants than almost anywhere on the planet. Even if they're spies, they're polite enough not to shit up the neighborhood like most immigrants do.
The only concerning issue with Chinese attending US universities is that they're displacing Americans from STEM positions. Beyond that, China needs to do something with all of the dollars that we spend on the cheap shit they crank out. If they're not wasting it on overpriced college degrees, they're going to spend it on something else and that something else may have more grievous consequences.
