The Blue Tower (Unabridged‪)‬

Evelyn E. Smith was a popular science-fiction writer for many years. Like many science-fiction writers, he attempted humor in some of his stories, but unlike most of them, he achieved it. In this story, Earth has been taken over by a benevolent alien race that now does all the manual labor and allows humans to lead a life of leisure. Their motto is "be happy," and Earth has become a pardise. Humans, being what they are, though, can't leave well enough alone.
