Why We Use Money, or the Fisherman Who Needed a Knife

The film tells the story of a fisherman who, in a time before money existed, attempts to trade his catch for various items he needs, such as a knife and a hat. He faces challenges as each tradesman he encounters requires different goods in exchange. Eventually, they come up with the idea of using precious metals as a common medium of exchange, leading to the creation of coins. This new system simplifies trading, allowing the fisherman to sell his fish for money and easily purchase what he needs.
