When all of the areas of division between the North and the South, one main issue stands out. The South, who's economy was built on slavery, which had been inherited from the 1600's. The Southern leaders did not have a clear view of the future. The USA had been built for the part upon the political and social systems of Great Britain. They had ended slavery with compensation to slave owners. Economists like Adam Smith wrote in 1776 that capital invested in slavery was a poor investment compared to other areas, such a the opportunity afforded by the industrial revolution.With the slave population reaching 4 million, the South had placed themselves into a corner. They saw short term goals to preserve their economy and their society with slavery. They also had an overdose of pride.
All in all, Southern leaders wanted to remain a slave economy. As the North prospered with industrialization, the under populated South were wedded to a plantation economy.
About 620,000 soldiers died in the U.S. civil war. The Union lost around 360,000 killed (110,000 in combat) and the Confederacy lost around 260,000 killed (93,000 in combat).
About 360,00 Union soldiers and around 260,000 Confederate solders died in the American Civil War. A hole 5 percent of the states population was lost. Many were wounded. Back then the medican was so premature all they could do to save the wounded was to amputate. All they could amputate were limbs. Stomache wounds were fatal. More soldiers died from diseases than from battle wounds from the poor living conditions, and because many soldiers did not know how to live off the land.
About 600,000 people died from the north and south in the American Civil War (1861 t0 1865).
There are some published estimates that reach up to 650,000 US Civil War deaths.
The so-called total war strategy by the Union came into full play when President Lincoln appointed US Grant to be the general in chief with the title of Lieutenant General. Instead of trying to defeat the Confederate armies, Grant was determined to deny the enemy armies the supplies it required to conduct warfare. The more accurate term used today to describe Grant's strategy is a war of exhaustion. All possible supplies which were owned by private Southern individuals were either confiscated or destroyed. This disabled Southern armies to function properly. In addition to that, Grant had enough troops, more than any general in chief before him, to sacrifice the lives of his soldiers in harmful and unnecessary frontal assaults in the 1864 Overland campaign. Many people north and south found this to be intolerable.

It didn't lead to the Civil War, but it may have convinced some in the North that slavery should be abolished. However, the abolition of slavery was only one of the reasons for the war, and not really a major reason at that. The Emancipation Proclamation was not issued until the war had been in progress for two years and only freed the slaves in those areas "currently in rebellion".
