And you don't seem to grasp the fact all that money gets cut off with secession. The North was *STILL LOSING THE MONEY*.
Which is why they wanted a war.
It was those same banks that financed the importation of goods into the United States and thereby paid the Federal tariffs.
If you think the "banks" were paying Federal tariffs, you don't know how that industry works either.
And you agree that the vast majority of those imports were in Northern ports and were sold to Northern citizens.
I don't agree. The destination of those products cannot be known simply from the fact they were shipped to New York where the tariff was collected.
The *VALUE* came from the South. That *VALUE* gets cut off with secession. That *VALUE* is why the North would not let the South go in peace.
But somehow you insist that the South paid 72% of Federal taxes.
Produced. They produced 72% of the Federal revenue, meaning that without them, that Federal revenue disappears.
The government still loses that 72% of their income stream.
The North likely loses that 500 million per year trade with the South much of which only existed because of protectionist laws forcing the South to buy from the North.
As an independent nation, they could spend all that 500 million per year in Europe if they wanted.
The North stood to lose 700 million per year in revenue from their economy.
And that's why there was a war. The North absolutely did not give a sh*t about slaves. It was that money they didn't want to lose.
You would be totally wrong on that point. It appears you think King Cotton was a real thing. Turns out it was just a myth. See Industry and Economy during the Civil War The Northern economy grew rapidly during the war while “King Cotton” proved to be nothing but a myth. The South could not even feed themselves.
Again, you are pretty much ignorant of the facts.
