It is not difficult to see that greed is rooted in a sense of incompleteness and lack, a search for security, and ultimately a failure to experience the sources of fullness and peace within. Our world is full examples of powerful multinational corporations monopolizing natural resources to produce more and more profit, enlarging the gap between the rich and the poor. We can also observe how the capitalistic economy we dwell in and the whole industry we call marketing is designed to convince us to feel lack and consume.
Of course there is nothing wrong with having and enjoying things.
