““The United States in the twenty-first century is not very much like nineteenth-century Prussia (Prussia today isn’t much like Prussia then, either), but we still use its educational methods. We would never think of using its transportation methods (horsepower was literally horsepower), its communication methods (telegraphs), or its military technology (muzzle-loaders and bayonets). But government-run systems have a way of preserving themselves well past any rational point, which is why the United States still maintains the helium reserve it established for dirigible warfare—presumably to fight those nineteenth-century Prussians.””
