You would do well to read some other historical works on the War. It's not all South=bad, North=good.
Are you skeered a few Confederate movies will create a wave of support for butternut and gray!?
Quite the contrary. If you ever bothered to read any of my posts you would see that I totally support the economic roots of the war. It was the southern insistance on expansion of slavery to the west and Lincoln's total opposition to expansion that caused the war. The south had to have expansion if they were to stay economically viable. Sixty percent of their wealth was in the form of slaves whose population doubled every 15 years. With the markets for slaves nearing the saturation point and a number of southern states at a near a majority slave population, they needed new markets or the price of slaves would have collapsed due to over supply. That is not even to mention the social and security issues that would have developed as the slave population outnumbered the white population in their states.
Expansion was an economic and social imperative for them and Lincoln stood in their way.
