Chinanews, Beijing, December 19 – According to MSN China and iResearch, more than 50% of Chinese white collars believe a personal fortune of at least 5 million yuan is necessary.The survey was conducted online, covering 100,000-odd respondents.The average monthly income of a senior white collar in big Chinese cities is around 10,000 yuan. That is to say, it will take a white collar approximately 42 years to accumulate 5 million yuan of personal wealth. Thus it is an unpractical goal, despite the fact that 75% of white collars have faith in making investment.Being too covetous for wealth is bad for one’s health, particularly mental health.
