This box has a sticker on the top with a sign that reads; "money."
Somewhere, someone ships "the box" to someone else. That person then ships to another person. Everyone touches the box. Everyone opens it, looks inside, closes the lid, tapes it back up, then ships it to the next person. No one touches the contents. Everyone pays to see them. What makes the world go round? The sights, or the passing of money?
If the world was what made the world go round, the box would sit open for all to see, people removing and replacing the contents in equal exchange.
Yet the world is sealed in its box. People pass the box for money, hoarding the entirety of the world for their own amusement, but not touching for fear of lost "value."
What makes your world go round?
