Some useful educational discussions. For example, On whether money can buy happiness:
"Income increases also improved subjects' "emotional well-being" -- the quality of their day-to-day existences -- up until they reached the $75,000 mark. Earnings above $75,000 did nothing to improve subjects' daily attitudes. As income dropped below $75,000, test subjects also reported more stress and less happiness."
I am not sure that $75,000 is the threshold for happiness; but the point is that money can bring happiness only to a certain extent; beyond which people just get used to it quickly. On the other hand, the lack of money can certainly bring misery to a person as well as her/his family.
Steve Jobs found out at the last few moments of his life that all his wealth and fame turned dim/useless, and he should have spent more time pursuing/building more eternal matters such as love and arts. Let this be a lesson for us all.
