If you are making the argument that there is a monetary threshold that needs to be met in order to be happy (for a normal person) I would agree. What that exact threshold is I am not sure. In my youth I had enough to be happy on 40k a year even though I wasn't, but this was due to a lack of understanding/perspective.
If you are making the argument that money directly buys happiness, I would say this is a short sighted and incorrect view.
Did I summarize your point in either case above? What was your exact point? I'd like to discuss further.
Also, pertaining to the specific article, satisfaction and happiness (while similar) are two different things for me. I am not sure why they took a survey concerning satisfaction and assumed that "satisfaction" is synonymous with happiness for all participants.
