Shield, by Poul Anderson. It's a sci-fi book about a young scientist who, after an expedition to Mars (which is inhabited by an advanced race), invents a device that creates forcefields. Taking it back home with him, he doesn't realize all the implications such a device could have on the world (which has been through two nuclear wars and is now effectively ruled by an unwieldy American dictatorship) and he starts bouncing around between government agents and criminals trying to seize him to exploit his invention. It mostly reads like a suspenseful espionage story that happens to be set in the future, only slowing down during a stretch in which characters start barfing political philosophy at one another for a few chapters. Although I agree with a lot of what Anderson is saying, he could have maybe found a more elegant way to express some of this stuff, especially since dialogue is probably his weakest point as a writer. That said, stories like this are among the reasons why he's one of my favorite sci-fi writers.
