In this century, Money or more specifically 'Debt' is a major problem. Most this I refer to as issues, but money really is a problem no matter what way you look at it.
Many will argue money isn't evil and that it's people that misuse it or are corrupted by it. This sadly isn't so. The system we exist in is the problem, for as long as currency dominates our thought patterns we have an attachment. This creates an imprisonment psychologically and arguable spiritually. Can this problem be solved and how can we know for sure if currency is really out dated?
Firstly, let us look at the banking system and I'm going to pass this onto the Zeitgeist movement for the award winning doc**entary worth watching a few times in order to understand exactly how the system operates.
Upon understanding how currency is a problem, lets not look at how the human body functions. The human organism is a perpetual bio-chemical and bio-mechanical organism that exist on(in) multiple dimensions. So how does this complex being work? This being doesn't have currency . . . or does it? Actually the human body has something called ATP (Adenosine Triphosphate) which upon this bond being broken into ADP (Adenosine Diphosphate + Phosphate) creates energy. This the closest thing to a currency within the body. Why is the important to note as 'closest'? Well the human body has been so well designed that (Ignoring pathologies) most activities occur through it's brilliant design. For an example in order to help filter excess salt and water in the kidneys the body can increase the amount of salt excreted, water naturally wants to dilute (Osmosis) within the body and so follows the salt, this action doesn't actually take and energy (ATP) it is a secondary effect. In fact the Sodium-Potassium Pump is major use of ATP, but this one action actually causes a knock on of hundreds of other actions that don't require energy - all through design!*
It gets even better when one looks at how energy is made in the body as it is almost sustainable indefinitely with the correct inputs. Which in itself are also sustainable e.g. Farming creates food for use to eat, combined with clean water allows use to maintain the farm, also the farming itself is a form of exercise keeping the body healthy thus we can ascertain the cycle we mimic in life is a copy of what happens in our body [Yes we should farm more ^_^]
Why is this all worth mentioning, well my hero Jacque Fresco has actually done this and combine his engineering knowledge to enhance humanity but deigning a new system that surpa**** currency. Based a lot on the human body! By designing out the problems one can actively improve efficiency. A lot of people don't know that Nikola Tesla was so successful because all he kept doing was improving everything, each step on the way. The Venus Project goes that one giant leap into the future - those sci-fi fans of star trek will be impressed as it goes even further than the system they had as your see when you start the fun discovery of this incredible system.
*Please note this is a heavily simplified version I'd recommend your own research into the human body sincerely it is fascinating and brilliant.
