yes, yes, and yes.
but there is one more factor:
Asians have way higher IQs than whites.
In the past 150 years in China there were 6 major wars.
1. 1850-1864 Taiping Rebellion (My grandmother's great-grandparents lived this.)
2. 1894-1895 First Sino-Japanese war (My grandmother's grandparents lived this.)
3. 1911-1912 Xinhai Revolution (My grandmother's parents)
4. 1926-1928 Northern Expedition
5. 1937-1945 Second Sino-Japanese war (My grandmother)
6. 1946-1950 Chinese Civil War
Four social upheaval movements:
1. 1919 May fourth Movement
2. 1958 Great Leap Forward
3. 1966 Cultural Revolution
4. 1978 Chinese economic reform
There were also 9 famines during this period with total deaths of 120 million people during this period.
I think these events have contributed to a certain set of attitudes in Asians in the two generations after 1970, i.e Hungry and humble, as our ancestors were during those times, literally; the ones who survived, anyway.
Either way, I don't see an argument against the article's main thrust, namely "working children into depression, anxiety, and burnout is bad."
