I listened to Tyler Cowan interview Dave Barry, and they spoke about humor in partisan divide. Barry is not the first I have heard mention it, but much current humor does not cause laughter, and not even a smile or chuckle, just the grim satisfaction of having said something mean about the other side that you know your people would approve of with a knowing look. Grim satisfaction has replaced laughter. Oddly, it was traced back to SNL, and the idea that they had greatly improved humor by bringing in silliness to go with topicality (and really first-class silliness, I might add. Killer Bees. Cheeseburger, cheeseburger...), but also sown the seeds for its destruction with their increasing political meanness.
Then I saw the FB pages of some relatives, who used to be funny people, and knew that it was true. I feel some guilt in the case of my younger brother, as it was I who originally taught him this.
I am trying to think of political humor from any side that is actually funny. The closest I can get is people who go against type and play on that for humor.
They spoke highly of Robert Benchley for written humor, but allow that his short films are at least from a script.
