7. The Civil War: $79.7 billion
Seventh on our top is the Civil War. As one of the deadliest conflicts in American history, The Civil War pitted the Union states opposed to slavery against those that were pro-slavery.
It turned Americans against other Americans in a war that split the nation. Yes, it costs the nation a hell lot of money, but it was a fight that needed to be fought.
A war between the Union and the Confederacy had to happen because they needed slavery to be abolished.
Some may think that the real reason of the war was more about political control and money than about freeing slaves. What do you think? What was the real reason behind this cruel war?
