It didn't just come, it was engineered by people who wanted to take the Government into receivership, using a ruse thought up by John Quincy Adams after the Nullification Crisis showed that Southern agricultural interests were finally breaking with the Northeastern trading interest. All during the Federal period, the Tidewater planters had voted with the New England merchants, but Nullification presented a systemic crisis. The merchants had alienated the planter aristocracy by overreaching for their money. The old alignments were breaking up.
Soooo .... other means of securing the South's cooperation and meek payment of the Yankee ransom-tariff needed to be found. Quincy Adams came through and delivered the top-line intellectual justification, or "theory", for a new Union founded squarely on Northeastern self-interest only.
Marxist much?
It's not "Marxist" if that is what happened.
You've read Robt. Toombs's speeches about Southern complaints about Yankee domination of business and use of the federal government for self-dealing at the expense of other sections of the country. Was Toombs a Marxist?
