If your intention to pursue a Ph.D. is driven by non-academic "whims and desires", I would suggest that you go for an MBA or specialized Master. An MBA from a top program (e.g., Wharton) can land you a lucrative career that is more high-paying than a teaching school faculty position.
I revisited ananawhc's original query, and it seems to be only concerned with career placements that a PhD promises -- specifically, teaching schools and their potential in helping her achieving her nonacademic goals and objectives, without any reference to research interests. These two are disparate topics.
