In 1857 bitterness arose between the sections increased, as millions of Southerners - including slaves - remained prosperous and well-fed, but in the North some 200,000 had lost their jobs, and "Bread" riots occurred in the North, not the South. Parson Brownlow of Tennessee stated that Northen industrialists should refrain from attacking slavery, and instead find means to feed the starving Northern poor.
The net result of the Panic of 1857 [the worst up to that point in time] was a massive shift in fortunes, as money vanished from Northern pockets and found it's way South.
Anyone wanting to understand the economic motivations of Lincoln and the North should study the Panic of 1857 and it's aftermath, and understand the increased bitterness and hatred of Southerners and slavery.

Of course it must, otherwise the secessionists were morally and legally correct, and Lincoln and his cadre were the despots and dictators.
Again, during the convention, one James Madison, motioned for the power of the militia to PREVENT SECESSION, and force the secessionists to rejoin the union. Giving credit where it is due, the framers REJECTED his insane motion overwhelmingly.
Those framers knew that they had seceded from Great Britain, and were about to secede from the Articles of Confederation and Perpetual Union.
