grgDai,

Life without happiness is no life. I have seen many wealthy people who at their last stages crave for one drop of happiness.
By the way, I hope you understand the difference between being "well-off" and being "wealthy". The tone that you used to express your opinion certainly shows that you don't understand what happiness really is.
So, please make sure that you understand the question before you start calling other people's question as dumb.
