I agree with most of your points. However, I can't quite agree with idealizing China completely (frankly, I don't think any government in the world is all that great). China has its own deep structural issues, such as the massive disparity between Tier 1 and Tier 2 cities, the grueling 996 work culture, and the 'Tangping' movement. That being said, I can absolutely vouch for your deep understanding of Korea.
