Dispite what most people think, money is a tool, nothing more then that. I think your problem with money is how people value you it so much to the point of screwing each other over for it. How ever money is necicary as no one works for free. Even back in the days when people bardered, they traded goods and services in order to servive, how ever the barded system is very unreliable as some times you are simply unable trate with some one do to the fact that during some point in time no one will have a need for your items you wish to trade which then makes living very difficult. An example of this is say you produce blankets or baskets and you traid them for chickens, well what if the farmer/s don't need blankets or your baskets, you go hungry. Currency was a simply salution to the barder systems unreliability and it works very well as long as the two parties agree on the price or the items over all value.
This is the roll of money, as I said, its a tool and nothing more.
