Monument
 A nondescript spacer with little education named Cerne Obrien finds a cache of extremely valuable "retron crystals", but crashes on an idyllic planet before he can sell them. The planet has a single continent, inhabited by humans with a Polynesian culture. The natives live contented lives, hunting a horrific sea-creature called the koluf, which constitutes almost their entire diet. Obrien uses his surviving technology to rid the area of several pests, and eventually marries. The natives come to call him the "Langri", a title of deep respect. Obrien lives a peaceful life, watching his descendants grow up, but when he realizes he is getting old, he begins worrying about the future. Unscrupulous developers would inevitably attempt to turn it into a resort. Obrien could handle them if they arrived soon, but he cannot live forever. He has bright young people sent to him. He begins to teach them "the Plan". It is difficult to teach the non-technological natives all they need to know, as they have little concept of modern galactic society, but he manages it. His best pupil is a young man named Fornri. Even as Obrien lies dying, a developer called Wembling arrives to illegally prospect for minerals. The people, led by Fornri, put the Plan into effect. They first capture Wembling and his men, and the crews of the four scout ships sent to find Wembling. The Navy eventually arrives, official negotiations ensue, and a treaty is signed recognizing the planet under the name Langri. The people of Langri fine the Federation for illegal landings. In due course, this (and Obrien's retron crystals) allows the people of Langri to hire a law firm as specified in the Plan. Eventually Wembling realises the planet's potential. He sees to it that the record of Langri's Galactic treaty is lost and procures a charter to develop a tourist resort. The construction drives away most of the koluf, and the people begin to starve; their adaptation to the environment has eliminated their ability to digest "normal" food. The starving people of Langri fail to get a court to stop Wembling; he has a seemingly valid charter. Meantime, Wembling's niece Talitha, and his hired (and fired) anthropologist Hort form a relationship, and sympathize with the natives. They discover Obrien's wrecked craft and read the log, including his notes on the Plan; they are amazed that one man could have created such a complete and detailed scheme, including Obrien's masterstroke. Fearing to interfere with the Plan, they keep their newfound knowledge to themselves. In accordance with the Plan, the people of Langri have been secretly learning to read. After having achieved the required high literacy rate, they successfully petition for membership in the Galactic Federation. The Plan then enters its endgame: the duly formed planetary government imposes a tax rate of 1000%. Since the natives have few personal assets, they can easily afford to pay, but such an exorbitant rate would bankrupt Wembling. The developer mounts a legal challenge, but there is precedent that a government can impose any tax it wishes, as long as it is applied equally to all. Obrien knew of this obscure precedent and made it the cornerstone of the Plan. The new government of Langri plans to build schools, parks, and hospitals to benefit the people. In the short story version, it even hires Wembling, admiring his ruthless energy, if not his morals. (In the novel he departs in disgust after trying to offer the new government a deal on a hotel.)
