Karl Hess was a noted speechwriter (for Barry Goldwater among others) and author, and later in his life became known as a tax resister, welder, and market anarchist. In this video from a National Libertarian Party convention in 1985, Hess speaks about how the invention of various tools throughout history has changed the world for the better, in many cases despite the best efforts of bureaucrats and politicians. He also gives general remarks about the libertarian movement and gives advice regarding his own brand of simple, harmonious living.
