Frankly I think they feed off each other. The bigger social misconception, IMO, is that "success" is often specifically *defined* by our culture as financial and/or career success. There are many other ways to be successful, and in that context, yes, they feed on each other.
But the slavish pursuit of "success" in terms of trying to get rich and get the corner office can leave people miserable, because they don't know how to be content with "enough" and instead burn themselves out and damage personal relationships by pursuing "it all."
"Hey, for every ten dollars, that's another hour that I have to be in the work place. That's an hour of my life. And my life is a very finite thing. I have only 'x' number of hours left before I'm dead. So how do I want to use these hours of my life? Do I want to use them just spending it on more crap and more stuff, or do I want to start getting a handle on it and using my life more intelligently?" -- Joe Dominguez (1938 - 1997)
