Unlike news companies, commentators do not gain monetary value from sensationalism.
Authors of articles are generally more informed than their pieces suggest, but their editors step in and make the story "pop" for readers in order to generate clicks. This often involves removing nuance. I believe that most major news organizations make an honest effort to be factual, but there's a lot of room within the facts to be misleading.
A commentator that is an expert in the field is not constrained by an editor, and can in a few paragraphs give a more realistic and accurate assessment of the phenomenon.
When I read articles about things in which I'm not knowledgeable, I don't trust the conclusions until I see high quality comments(or tweets) that confirm the thesis of the article.
The modern Chinese psyche has been sculpted in large part due to the Cultural Revolution.
People who have grown up in comfort do not fully comprehend the effect of widespread hunger on a large population. Natural selection rewarded those that put their families above everything. The families that did not died. Parents that did not do everything in their power to feed their children watched them starve to death in their hands.
Many things about modern China can be directly linked to this shared national pain.
The absolute, obsessive drive of Chinese parents to have their children study and reach a higher station of life is a direct result of the culture of hustle instilled by their parents and grandparents. Devotion to families, incredible work ethic, creativity and innovation can all be traced back to the skills necessary to survive the Cultural Revolution.
However, many of the problems in modern China can be linked to this phenomenon. Bribery, open piracy, corruption are common in every walk of Chinese life. Chinese people put themselves, and their families, first and they've never had a compelling argument against it. People in the West believe in their institutions in a way that doesn't exist in China.
But, time will change this. There is clear precedent in the West that each successive generation that grows up outside of poverty will be less and less cutthroat compared to the generation prior.
It's a very simple cause-and-effect.
