Fake Sneeze! Real Sneeze!
In a world where poverty and prosperity co-exist, sneezing isn't a reflex. You can actually buy a sneeze to unclog your already dirty nose, but it's expensive. This world has only 2 towns. There is an impoverished town where people live in the slums and wish to sneeze, so they pretend to sneeze by only saying "Ahh-choo" a few times. The pollution makes life harder in this town. There is another town alongside this one. This is a flourishing town where gold, diamonds, mansions, and cash reside. Anyone here can buy an actual sneeze instead of pretending to sneeze. As time goes on, these two towns can switch sides. One day town 1 is flourishing and the other is impoverished. Then the next day it's back to normal where town 1 is impoverished and town 2 is flourishing.
