Well firstly, "tariffs" is convenient term to dodge the real issue; 60% of the total production of the South going to the North. Tariffs" was a part of that, but all the protectionist schemes created by DC worked to the same purpose. The "Navigation act of 1817 gave Northeastern shippers a virtual monopoly on shipping, which they did with a great deal of gouging. Subsidies for Northern shipping also made it difficult for Southern shipping to compete with them. It's hard to make a profit when your competition starts out with a large chunk of operating cash thanks to the government.
Protectionist laws which made European products uncompetitive and so Southerners had to buy domestic products at much higher prices.
What the Northern controlled DC government was doing to the South went way beyond just "tariffs".
Secondly, how can you say with a straight face that "Slavery" was the cause of the war, when the Northern government offered them unlimited slavery on a silver platter? How can you say that with a straight face when there were 5 Northern slave states that didn't get invaded for having slavery?
You just say what we've all been taught, but the difference between you and me is that I started questioning these claims when I started noticing pieces that didn't fit right.
Actually, the country had compromised and revised tariffs numerous times before the Civil War.
It wasn't about just "tariffs". It was about protectionism, gouging in shipping, banking, warehousing, insurance, and every other hyped up cost the North imposed on the South for carrying their goods, and laws preventing them from hiring foreign ships to do the work. It was about the money being collected mostly from the South's export trade, and then spent in the North with no benefit to the South.
What could not be compromised though was slavery because the South refused to consider compromise.
Well the North certainly did compromise on slavery. They offered the South all the slavery they could possibly want. (Corwin Amendment)
Seems like both sides were in agreement on the slavery issue, so that wasn't the real sticking point for the war. What was the one non-negotiable thing? "You can't run your own trade and get out of our taxes."
That was the thing the North would not compromise on.
Slavery? Sure! Have all you want! But you better *PAY* us our 60%!
I recommend that you take the time to read and consider the references to slavery in all the confederate articles of secession and Alexander H. Stephens "Cornerstone Speech" explaining the reason for secession.
I am familiar with that. I'm familiar with all the (3 or 4) "secession documents". I'm also quite aware of which direction the money was flowing, and as a very cynical man, I have long discovered that you can always find the truth by following the money.
People lie about their honor, their morality, and their integrity, which is why you cannot trust what they say. You have to look at where the money goes.
I'm likely familiar with all the arguments you will put forth, but I very greatly doubt you are familiar with all of the arguments I might put forth. Specifically this argument isn't mine, but it seems plausible to me.
Syndicated Columnist Paul Craig Roberts has a very interesting explanation for why some people in the South claimed secession was about slavery.

Moreover, as much as the North would, in a pinch, promise not to interfere with slavery, the North would not enforce the highly unpopular Fugitive Slave Act. That put slavery on increasingly shaky ground in the South because slaves could and did flee North to freedom in large numbers.
Lincoln knew that at the start of the Civil War, fighting to free slaves in the South was a less persuasive argument in the North and in essential border states than fighting to preserve the Union. Instinctively, former trial lawyer Lincoln shaped and pitched his case to the country so as to secure victory.
Again, go read the Confederate secession ordinances. Slavery was in every one of them. And the Cornerstone Speech declared that slavery was a positive good because it subordinated the inferior Black race to control and supervision by Whites. Lunacy -- and a clear example of why the Confederacy is worth close study as an example of how essentially good people can believe in foolish and evil things.
