"Greed is natural part of the human experience" according to who? Humans are built for sharing because every economy outside of the west is a sharing economy. Money is a false, abstract concept that was CREATED by man to control resources and monetize other people. Before the invention of money, people shared. This is widely accepted. Greed is not a natural part of the human existence. I live every day without feeling greed. I buy only what I need, I consume only what I need, I drink/eat/wear only what I need. I am aware of what greed feels like, but I haven't felt or indulged in that feeling since I was a child/teenager.

Your comment that

Anyone who proclaims that we should do away with it has some dangerous totalitarian streak in their personality. Humans can't be molded like play dough and if you try, you'll have to use the power of the gun or the treat of violence.

Loaded with incorrect assumptions. Firstly, I'm the last thing from a totalitarian. So in that you are already incorrect. I live my life by natural law and have no trouble allowing others to do and be themselves while still maintaining my integrity. Secondly, humans are rational creatures, there is no need for violence to convince people that greed is bad. When you look at the state of the economy and the local environment it should be obvious that greed is a horrible thing that has no place in a civilized society, just like violence has no place in a civilized society.

You agree that 'the law of the jungle' should not prevail despite humanities long history of violence, yet you do not question the premise that greed should be allowed despite its very short run in societies. Remember 99% of known human history was hunter gatherer. You cannot be very greedy in a society like that because everyone knows who you are and knows your contribution. If you don't share in both the work and rewards you get cut off=you starve.

So no, I do not think your post follows, it is not historically accurate that greed has always been present nor does the evidence support the notion that greed is all pervasive and needs to be 'managed'. It is the management of greed that allows it to grow to proportions that are not commensurate with its value as an emotive response.
