"@Bart, you are right; we need to interchange things to survive. We cant sustain ourselves for more than one day without other persons services and products like transportation, bakery, hair cutting, food, etc. Dont get me wrong, I dont support the idea of living in a cave, praying we dont get hungry - lol. I think the idea of living without money will make us rethink what we trade in the sense that we will become more aware of the two-way nature of every purchase instead of the automatic one-side paying behavior is now (I think money has reached a kind of blind side). If for a moment we become aware we are interchanging things, then we will value what we want and need and what others want and need. e.g. if I need bread I can give the milk I have to my neighbor (assuming he needs milk), but if I have a fancy watch and give it to my neighbor who is starving, no use for him neither me (I wont get bread). This will make impulsive buying fade away and so resources usage will get back to balance. "June 21 2012 on Live 1 Month Without Spending Money.
