Ball Stand

     A homeowner sells used golf balls. His property borders a country club. The balls land in his yard.
     Nobody in person collects the money. Customers drop cash into a jar. An honor system prevails like at a farm stand. I doubt anyone steals the money or the balls. By and large, people are honest in this suburban area. They can be trusted.
     Would this honor method succeed in a city? Probably not. Even though plenty of city dwellers are honest, it takes only one thief to empty a jar of money. And thieves are more apt to live in cities.
    Sometimes you must trust people before you can trust them.
