Don't know when or where I read it.
The story, told with a humorous slant, highlights a small town that implements a mix of libertarian and socialist philosophies, much to the distain of two grumpy men who apparently argue continually about how the leadership should be "pure" in their policies, one way or another. A visitor talks to the mayor(?) who explains that the town adopts what works, regardless of what the idea might be labeled.
I am writing a version of this story and want to credit the story and Anderson.
