Greed is a word that I feel is misunderstood. Everyone wants the best for their families, and would not see themselves as being "greedy" in obtaining it, why others would hold a different opinion. It all comes down to a point of view. My personal belief is that we should work hard every day to realize our potential spiritually, financially and morally, thus we grow evenly to be a more useful human being in our world. I think having these three components in continual harmony is key to realizing success and find it not coincidence that some of the most successful people in history, have also been some of our greatest philanthropists. So greed in this sense, can be looked on in a positive light, but when greed leads to an obsession of a thing, you become out of balance and self destructive to yourself and others.
