Hello Bro Joe K. Long time no see.
Certainly the war was about slavery and that means money.
In 1860 four million slaves gave the South a net worth of $3 billion dollars.
More than had been invested in rail roads and factories at the time.
Interestingly I recently read the story of a mortician, Rufus Weaver who had been contracted by the families and the Confederacy to exhume and return the remains of Confederate soldiers killed at Gettysburg.
He exhumed dozens and dozens of bodies, a grim task to be sure and he never got paid.
He calculated at the time he was owed $6,000 dollars.
Money in live people, not dead ones obviously.
Confederate chislers.
The was was about STATES RIGHTS, which they were promised when they signed the constitution.
Slavery was just the vehicle. It was a just cause, don’t get me wrong- but the issue was TELLING states what people had to do. Like buy health insurance.
In reality the North would have been devastated financially if the south withdrew- that why the war was fought about keeping sacred “The Union” (genuflect)
Which was resulting in about 750 million per year going into the pockets of the Northern wealthy.
