I found the poll to be lacking sufficient options. There are many reasons that Americans might be relatively careless compared to Scandinavian countries. We are far more diverse than Scandinavian countries with a history that includes genocide, slavery, attempted separation of the North and South, Jim Crow, and numerous wars and 'police actions', including the Cold War with the PRC and Soviets. Part of the answer to any question about what's wrong with America is 'history'.
