It is a reasonably established fact that the several tariffs greatly favored the Industrial north and heavily burdened the agricultural South. The 1828 so-called “Tariff of Abominations” produced roughly an 80/20 percent South/North revenue stream into the treasury. Lincoln promised to triple the rate; and, in his inaugural address, to enforce collections with the force of arms. Obviously, the import-dependent south was none too pleased.

Established by who?
The 1828 so-called Tariff of Abominations produced roughly an 80/20 percent South/North revenue stream into the treasury.
Why did the South consume 80% of all imports. What were they importing in such large amounts? In his speech to the Georgia legislature, Alexander Stephens said the north accounted for three-quarters of all business abroad. And that may have been high.
Lincoln promised to triple the rate; and, in his inaugural address, to enforce collections with the force of arms.
He also said he would deliver the mail and make appointments, though in none of them did he threaten to do it through force of arms. Not even tariff collection.

He goes into great deal on tariffs, post rebellion. In neither of his two chapter on pre-rebellion tariff does he make the claim that the South footed four-fifths of the tariff bill.
