Unfortunately, heaven is other people too
Family Circus, 5/28/23
The Good Place was a great philosophical afterlife sitcom, and in its later seasons you learn that the titular Good Place (its cosmology's equivalent of heaven) hasn't had any new arrivals in centuries, because an increasingly complex and intertwined society has made it impossible for a living person to make any choice that doesn't directly or indirectly cause harm to someone else. Today's Family Circus, however, posits the flipside of this scenario: due to an overall lowering of human misery (in the long view violence worldwide really is probably lower now than any other time in history) plus a radical increase in population, heaven is simply being overwhelmed by a number of souls that its infrastructure simply isn't equipped to handle, leaving the virtuous dead to sit packed together on clouds with little to do occupy the rest of eternity, like inmates in an open-air prison camp. It's not surprising that these spirits need to occasionally sneak back to the plane of the living to experience just enough sensory input to keep them from going mad!
