Wonder how deep and widespread this dissatisfaction really is, beyond a simple worker dispute in a country where so many other public disputes are not tolerated.
Sure, you can find anecdotal statistics and generalize it, but my impression is that the extreme performance culture not only is accepted, but an integral part of the Chinese school system and upbringing. The 6 to 1 model with; 1 child, 2 parents and 4 grandparents who project their expectations and family reputation on to the child seems to structurally strengthened this. Not to mention that the neighbouring countries have practiced this for decades.
Recently hung out with a Chinese women in her twenties and to her studying 12 hours per day for a child was completely natural.
