What the fuck does that have to do with rich people using propaganda to pit Americans against each other. The civil war was a great example of the American people getting owned by the rich as always.
Instead of the wealthy sorting it out they used Americans as pawns in a senseless war. It was a garbage war that produced garbage results.
We still treat blacks like second class citizens to this day.

Saying the civil war was only about slavery is a bunch of bullshit. Primary reason, sure.
