I am not able to read the article (blocked for newly registered domain at work) but I think you took an incomplete understanding of humanity from your story. It's not that the rich guys had silly things they were unhappy about, it's that the nature of human unhappiness is fractal across many domains, including wealth. You think the things they were unhappy about were silly because they solved all the problems you ascribe value to (because you experience(d) them directly at your wealth level), probably by throwing money at it and they have found new things at their higher wealth level to repeat the pattern of human unhappiness. I do agree that your last paragraph is the antidote to this fractal pattern of unhappiness though.
