“Who wants to pay for higher tariffs?”
Tariffs were not high in the years just before the Civil War. This has been pointed out to you time and again. Why do you keep lying?
It may have been said repeatedly time and time again, but that isn't the same thing as having been pointed out to me.
Tariffs varied depending upon what was being imported, but they usually were high on things the South wanted, and usually low on things the North wanted. (and low on things for which there were no domestic producers.)
But the issue of tariffs is mostly a red herring to the cause of the war. Tariffs were only a small part of the reason why the South wanted out of the Union.
A bigger reason had to do with losing about 40% of their profits to New York. New York controlled the shipping, the banking, the warehousing, and all other related matters, and all of this took a big chunk out of the profits for their exports. The Navigation act of 1817 gave New York a virtual monopoly on shipping, and so Southern producers were stuck having to pay rates that were just under the fines they would incur for using foreign ships and/or crews.
If you want to hear a contemporary account of their real gripes, this man did a fair job of covering them, though by no means complete.
