Greed v Discontent

is there a difference between discontentment that leads to the accumulation of stuff (think shopping sprees) versus the better-than-the-joneses never-ending pursuit of wealth?
i mean to say feeling unfulfilled and discontent is quite a different malady than being greedy, but do they have necessarily different cures?
the solution to discontentment is to be content. content with who you are, what you have, where you fit in to the world, the grand scheme of things.
the drug of greed however seems quite different. is it necessarily due to a lack of fulfillment? for i think many greedy people are fulfilled, do have all they want, but simply enjoy the endless pursuit of more. i don't know whether this is a condition that needs a cure. i don't know whether the greedy person has a soul that cries out for meaning, for water to drink that will truly satisfy. i don't know whether this person needs anything? whether they need jesus?
the person who seeks contentment, however, will, and can truly be content when they find and accept jesus, the water that he brings.
but what, if anything, can we bring to the greedy person?
