lj: I was aware of the taxation issue. Southern States imported a lot of goods from England that were taxed.
But slavery was a very big issue. If slavery were eliminated, the wealth of the people who controlled Southern States would be greatly diminished. No free labor, no big profits.
I think there is a parallel situation now, between the power center of the North, New York City, and the power center of the South, Houston. I have thought for quite a while that this is behind the attack on fossil fuels. Take down fossil fuels, take down Texas. Actually, it might be as plain as the nose on your face.
