In an attempt to show us how fundamentally strange money is, in Money: The True Story of a Made Up Thing by Jacob Goldstein, says that “how societies move from monies with intrinsic value (commodity currencies, like salt, or coins made from precious metal) to paper currencies that are valuable because they are tools”. According to Goldstein, “Currency is a national bedrock that sits alongside anthems and flags”. To show us this, the review Money: The True Story of a Made-Up Thing shows that currency is an entirely made up thing backed by the flags or whoever is behind it, and it’s value is based on a simple mathematical number or its scarcity, also known as inflation. Finally, in the Money: The True Story of a Made-Up Thing review of The Fiction That Makes the World Go Round, tells us that paper currencies such as precious metals, paper currencies, or a number on a screen somewhere is all used for the exchange of goods or services, as well as being used as tools. But, Jacob Goldstein says that money is also nothing but a printed I.O.U that shows nothing besides more paper money later on.
