I disagree. Greed and sustainability cannot exist simultaneously. Greed will only lead to the disaster, infinite growth in the world of finite resources will lead to disaster. Greed even hampers progress. Example, the current trend is towards applied research in nearly all fields because greedy corporations need practical results as fast as possible. The basic research (the vehicle for discovery) is practically abandoned. This alone hampers development. And I do not even go to what greed based society does to creativity.
