The cause was slavery….you really do drink the look aid don’t you?As I said, southerners are more laid back. The slaveowners with the biggest plantations were all northerners, they were constantly working and were constantly pushing their slaves to work harder whereas a southerner owned plantation would have the slaveowners sleeping in, the slaves would be sleeping in, the bare minimum amount of work would be getting done(this is where the image of slaveowners sitting around comes from but the slaves on those plantations were largely doing the same thing because that was the culture)and eventually the plantations owned by the northerners would win out(which makes the hatred of the Confederacy and the South ironic because the slaveowners whom the South were fighting on behalf of were northern born).
The clash between rural and urban today mostly has to do with urban degeneracy and high crime and a similar clash of lifestyles as the North and the South.
Just read the succession documents from South Carolina…
They summarize if for you since this seems to be a tough concept for you yo grasp. If you need a video instead let me know. I’ll get you one. Reading can be difficult.
