Just for fun, here are some answers from existing writers.
Economic: There’s no such thing as “wealth” or “poverty”. Any material good or service can be obtained simply by asking. This is the setting of many SciFi novels about post-Singularity worlds (see Charles Stross or Iain M Banks or even Cory Doctorow sometimes).
Sexual: The Left Hand of Darkness by Ursula LeGuin. People have no sex drive normally, and no gender. Instead, they periodically enter a phase similar to estrus, at which point they acquire a gender (male or female) based on environmental factors. (I was going to use the world of Simoun originally, but that might be a bit too blatant).
Governmental: Administrators, legislators, and other public officials are determined by lottery. Robert Sheckley had a book with that setting, but I forgot the name...
Technological: Technically, our current world is already pretty close. In addition, any “high fantasy” book with magic in it would qualify.
Cognitive: Blindsight by Peter Watts, especially the alien parts.
