What is money?
Imagine a world before cash or cards, where trust was the currency. That's flexible social credit—keeping tabs on favors among family and friends.
It worked well in small circles, like swapping chores or borrowing sugar. But as communities grew, it became hard to track who owed what to whom.
Without a formal system, it couldn't handle the demands of larger societies. That's why we needed something more universal, like money, to keep things fair for everyone.
