You will not listen to contrary evidence.
Everyone is entitled to their own opinions.
I have listened to evidence from the pro-south side, and from the pro north side.
I don't find the evidence of "the war was only about economic domination of the North" to be persuasive.
Probably a factor. Probably not the dominant factor.
I don't recall seeing anything that looked like contrary evidence to me.
We have the financial records for this time period. Perhaps you haven't seen them?
Now if you will take those figures from both the North and the South as 100%, then you will find the South produced 72% of the total, while the North produced 28% of the total.
So how was the North getting it's hands on more than 28% of the European money?
The North had 4-5 times the population, yet were only paying 1/4 of the total tax burden?
How does that work?
Probably a factor. Probably not the dominant factor.
700 million dollars per year in a 4 billion dollar per year GDP economy is a pretty serious factor.
The South produced 200 million per year in Trade value with Europe, and 500 million per year in Trade value with the North.
There was 700 million dollars per year at risk for the Northern power structure if the South got away from them.
But no, they only cared about the poor slaves whom their representatives voted to keep in slavery forever. (The Corwin Amendment.)
