It’s like being in a crowded football stadium, watching the crucial play. A spectator several rows in front stands up to get a better view, and a chain reaction follows. Soon everyone is standing, just to be able to see as well as before. Everyone is on their feet rather than sitting, but no one’s position has improved. And if someone, unilaterally and resolutely, refuses to stand, he might just as well not be at the game at all. When people pursue goods that are positional, they can’t help being in the rat race. To choose not to run is to lose.
