Having faith in something we never see is a characteristic many people share. Our faith in religion, money and many other things differ from person to person. In the NPR broadcast it talks about how money was invented and the idea behind it very odd and interesting. It talks about a country in Micronesia using limestone rocks as currency. It was odd because the people of this Micronesian country rarely moved these stones when used to buy things. If one were to buy a chicken they would simply state that this rock is now in the possession of another person. This works because people have faith in their money that others will accept the currency. For something as useless as a rock people used it to trade for something like a chicken which can produce eggs and meat which is extremely useful.
Looking back at different currencies and systems of trading fro goods they all had the same basic principals, one being faith in the other persons good or currency. Without their faith it would be worthless. We put a price on the things we buy this creates the supply and demand. If a lot of people want something they put a higher price on it and if they were to have too much of something customers would go to the cheapest place to get it. It brings to question who puts the value of money such as the Dollar or others like the Fei. The value of money is given by the person using the currency and the local economy. If people are willing to pay more for something they will do it increasing the value of the money.
Milton Friedman also has a say on this topic studying the culture of the Micronesian currency and comparing it to the US Depression. Saying what the Germans did to their colony was very similar to what the French did to the US. Something so illogical caused a huge ruckus. It is pretty interesting how we can put our trust and faith into a money system that has no value other than what they think it is worth. The Fei was in essence is the very same as the US Dollar except in a different form. This form of currency one based on faith is very dangerous because anyone with enough power can control entire economy like the Germans did with the Yap and took away their currency. Until there is a perfect system it will always be a game of faith when it comes to currency.
