The great virtue of capitalism is that it adapts to ruinous conditions and even finds ways of turning them to advantage. The United States in the mid-nineteenth century was badly suited for a single currency and a single economic structure, as evidenced by the Civil War, which was provoked as much by single-currency tensions as by moral abhorrence to slavery.
资本主义的一大优点是它能适应破坏性条件甚至找到办法把它们转化为优势。十九世纪中叶的美国十分不适合采取单一货币和单一经济结构，南北战争就是明证，单一货币紧张局势和对奴隶制到的痛恨都是战争爆发的原因。如果加里波第没能统一意大利，说不定意大利会比今天更好。
