We’re driving through the mountains of France talking about affluence. Looking at the map this morning, John noticed that affluence is the French word for the tributaries of a river. He wonders if the word once suggested a great river of wealth flowing into smaller affluences. Was it comforting for people to think of money replenishing itself in a regenerative cycle with the rains? Along with affluence, there are liquid assets, and trickle-down economics, and the rising tides that float all boats. Why is water so often a metaphor for money? Perhaps because we like to believe that our economic system is naturally occurring, not man-made. Maybe the movement of money feels inevitable if you imagine it as water, with only blameless gravity participating in the accumulation of wealth.
