Kurt Vonnegut (1922 to 2007-USA) was one of the most popular post WWII novelists. He wrote such highly regarded best selling works as The Breakfast of Champions, Slaughter House Five, and Cat's Cradle. Long ago, I read all his major novels.
I was very happy to recently find a short story by Vonnegut online. "Harrison Bergeron" is a science fiction a story about the future of the USA. It is written in a very simple kind of matter of fact style. I think it could be read by and used as class room material for children 12 and above but it is by no means a children's story.
"Harrison Bergeron" is set in a future American where everyone by law is equal to every one else, not just equal in theory or in law but in fact equal. If woman has the unfair advantage of being beautiful, she must wear a bag over her head. If someone is above average in intelligence an implant is placed in their brain which can detect advanced beyond the normal processes. This implant can cause severe pain if one tries to think above the average level.
We never learn how or why this came about. We do not learn who is running things. We do know that whoever figured out how to do the brain implants was themselves using way above average intelligence in pursuit of social goals.
There is a big action scene at the end and I will not spoil it.
