Also the your belief that greed is the basic human instinct is a good indicator of how you have been conditioned to support this mode of production.
Learn some stuff about that:

It has been scientifically established that the social function that sets humans apart from other animals and allowed us to become intelligent in the first place is our capacity for cooperation. We have big brains because it takes a lot of processing power to recognize facial expression, and that is 90% of how we interact with other members of society.
Cooperation, not greed is the basic human template. Greed is conditioned behavior and not inherent to the human animal and if you will actually read this book, which I have pointed you toward about ten times, you may come to understand how wrong you are to believe that. There are many examples of human society's in which greed is unknown. All of early human history for a start. In a hunter gatherer society being greedy is literally a tabu that is punishable by exile. Which is basically a death penalty.
