What was the issue between the north and south over free labor and slave labor?
The north believed that innovation and a free labor society was better while the south was greedy and felt that slaves were the best way to get rich.
they disagreed because the north didn't need slaves to support their ecoomy; it was based on things other than agriculture. however, the south's economy was totally dependent on slave labor to harvest cotton and other crops in the south. they refused to industrialize, keeping their regions mostly farmland, whereas the north had factories and such that didn't call for slave labor.
