That's the product of being brainwashed into a state of consumerism. Just do what you need to do to survive, and if you have more than you need give it away to someone who needs it. Boom! No money. Nobody starves.
Thats very ideal, but people have a natural tendency to hoarde nuts in case winter comes. I'm sure you do the same... your affluent enough to own a computer after all...
1. If you think "communism" is anything like what so called communist countries are trying to say they are your a fool. 2. communism is a good idea, but people are fucking power hungery and dumbasses so I don't see it working in the next 100 years.
