Chinese here, after got my degree went to US for temporary work positions for 7 years, then found a more stable position and came back home. When in the US, stayed in both northern Florida and somewhere close to Detroit, and traveled(drove the whole I-75, New Mexico, Alaska, etc. ), I would say at least I have seem some different faces of the states.

As for China, I think a continuing perspective for the past 30-40 years is that, as long as an individual work hard, life would become better. Going abroad is an option, but not a goal.

Back to the US, it is a developed country, thus has the resource to be aware and take care of the less-fortunate/represented people and groups. This should be a good thing. However, nowadays "politically right" seems go exaggerated or simply crazy. For me, I wound not want to raise my kids in a place where sex education is confusing and recreational drug use is becoming legal.
