Hmmm, I've been pondering this question since you first posted this entry. I'm wondering if the idea is somehow connected to prosperity theology, which suggests that "success" is granted to those who live according to God's wishes. By extension, this argument suggests that poverty (of pocketbook, of health, of spirit...) are the earthly manifestations of a life beyond God's favor. I don't agree with this doctrine, but I've certainly heard it preached in similar circumstances.

Preemptive disclaimer: I realize I'm oversimplifying things. And I probably shouldn't be typing this in a pre-caffeinated state. But I'll brave the flames by throwing it out there, knowing already that I'll learn from other people's feedback.
