Conflict, especially violent and deadly conflict, is far more attention-grabbing than peaceful cooperation. When there is peaceful and voluntary interaction, we’re accustomed to saying that “nothing happened,” but in fact lots of things happened: people went to work, farmers planted crops, investors financed new companies, and factory workers assembled useful products; people shopped; people fell in love; lovers got married; babies were born; there were birthday parties; life happened.
