The exact origin of the phrase "Fix the Money, Fix the World" is difficult to pinpoint, but its modern application was popularized by Dominic Frisby in his book chapter "Fix Money Fix the World," where he argues that addressing global economic issues requires fixing the monetary system itself.

The underlying idea that money is central to societal function is an ancient one, reflected in proverbs and the historical development of economies.

Origins of the concept:

Ancient Proverbs: The idea that money is fundamental to the world's functioning is captured in ancient sayings, such as the phrase that "money makes the world go round," indicating its central role in societal and economic activity, according to Better Blessings.

Historical Development of Money: The concept of money's importance is deeply rooted in the history of its invention and evolution from early forms of currency like cowry shells to gold and silver coins and the development of modern banking.

Modern application:

Dominic Frisby: The specific phrase "Fix Money Fix the World" was applied by economist Dominic Frisby in his work, where he focuses on how the monetary system's flaws contribute to economic problems like wealth inequality and instability.

Critique of Fiat Money: Frisby, in his work on the topic, argues that fiat money (currency backed by a government rather than a physical commodity) is susceptible to manipulation and inflation, hindering international trade and individual wealth preservation, notes Springer.

Focus on Monetary System: The central tenet of the phrase is that fixing the underlying monetary system—by moving towards sound money, for example—is the most effective way to address the world's broader economic challenges, according to Springer.
