Then why not define simply where motivation or incentive to improve or progress become the sin of greed? I don't think you can for any number of reasons. Simple example: times are good and you are making well above the normal expected returns on investment of labor, materials, fuel, etc to produce your product. Let's say you "hoard" some of that "excessive" profit, and a few years later that excess becomes the thing that keeps the company going and workers employed. Perhaps something happened that affected the supply and therefore cost of fuel, and you used used the saved income to keep prices in line and thereby grew market share. Greedy or smart business?
