How much money is there in the world?
Is there some way to calculate the total amount of money in the world? Is this different from the physical objects that represent money such as coins or printed papers? How do we know? What goes into the calculation of this amount? Why would these items be included and not others? Are there many bases of money, such as gold, silver, human labor? Why these and not others? Are there websites that track this information or must I build my own spreadsheet?
