A common story we are told is that money arises from the insufficiency of barter. Known as the “double coincidence of wants” problem, it is said barter was too limiting and a more flexible medium of exchange was needed. According to anthropologist David Graeber in his book, “Debt: The First 5000 Years,” this story is not true. To summarize his findings in ancient societies, what was found as “money” was delayed barter. For example, I don’t need item A now but I may need it in the future. I will give you item B and ask for A when I need it. This was the first creation of credit.
