I suppose the classic assumption that money or power bring happiness, when maybe it’s more about having enough to provide food, clothing, and shelter, along with enjoying a certain level of respect and appreciation.
It seems to me that happiness of a basic sort means having needs met, feeling loved and supported.
I find it hard to believe that the lifestyles of the rich and famous can automatically be equated with being happy. Yes, I’d rather have money than not have it, but at some point working for a living can turn into an endless pursuit, where people lose sight of what it means to simply have enough.
