Nearly three decades ago, a cabdriver in Moline, Ill., offered a unique expression of gratitude to a businessman discussing stock investments on a call about Alan Greenspan's "irrational exuberance." The driver, upon hearing the conversation, thanked the businessman for his success.

When asked for the reason behind this unusual sentiment, the driver explained his gratitude stemmed from two points. Firstly, the businessman's success translated into him being a paying customer for the cab service. Secondly, and more profoundly, the driver posited that success itself is a testament to providing a valuable product or service that satisfies customers, thereby contributing positively to the world.

This encounter highlights a perspective where economic success is directly linked to societal benefit, framing business achievements not just as personal gains but as contributions that improve the lives of others. The driver's simple yet insightful observation underscores the interconnectedness of economic activity and public good, suggesting that successful businesses inherently make the world a better place by serving their customers well.
