I agree with your points, except the part on jealously and warning against self-help. I view his life similar to investing, as he mentioned: being "long term greedy." I thought him and his parent's story illustrated this. It is unlikely that his parents had the best schooling in the world, but they were successful financially somewhat. When their son struggled in school, they enrolled him somewhere else and gave him more resources. He used that and achieve more by attending the most prestigious institution in the world. While it is likely that luck played a huge role, ie. China's market liberalization and growth, U.K. schools wanting to make more revenue, his stint at GS. He and his parents needed to be there in position the first place to take advantage of all of that. I do not think this is his point to warn against self help, rather than an examination of why and how he got to where he did.
Luck only comes when you are in position to seize it. Yes despite your best efforts, it might never come. But it can come when you never expect it because you are in the right place and the right time.
I agree with your statement, but if you turn around that logic, it is meaningless. Will you read about a blue collar worker's view on Chinese society? Probably not, since they are unlikely to have experienced it. Only Western elites will have been likely to experience Chinese society. Obviously someone who will be published in a magazine is elite. I am willing to wager than all the other writers are 'elites' in some way. As societies, we don't really want to read about some Cantonese kid working after school at his parents restaurant for 6 hours a day. We want to see success! That is why we tunnel so heavily on Cambridge, Stanford, and Goldman Sachs. Do you really think he would have been given a voice on this magazine if he was not affiliated with those institutions?
Reading about the west from a Chinese perspective is a breath of fresh air. Similar in background to the author, I have come to the same conclusion; that everything in life is based on a bit of luck and achievement. He also absorbed, which is somewhat unusual in my opinion the differences between U.S. and the U.K. I think he has a much more nuanced view of all three societies that he has written.
