Money. Money is the reason. Nothing but money. Greed is at the root of this. Greed is responsible for the deaths of 750,000 people.
......Income of the Federal Government 1857-1860
(Source: Historical Statistics of the US, Series Y 493-504, pg. 1114)
Total Income of the Treasury (Tariffs, public land sales)
Year..........Total Income..........Income from Tariffs
1857............68,965,000............63,876,000
1858............46,655,000............41,790,000
1859............53,486,000............49,566,000
1860............56,065,000............53,188,000
This shows the impact of the recession of 1857. Northern and Western manufacturing and agriculture was curtailed to such an extent that their exports declined and negatively impacted the imports that they would have produced.
Much lost tariff revenue showed up in much lower government revenue.
It is likely the Northern politicians used the situation to foster support for the sectional control of the Morrill tariff.
When secession began, US Treasury revenue declined rapidly. And the government was not ready for it.
Believe me, I know what you meant to say, but were just too shy to spit it all out.
No problem, you're welcome.
