Money was the reason Lincoln went into the war. He was a railroad attorney and represented them as president. They needed the union together. Lincoln had previously written about the States had the right to leave the union and his inaugural address said he could care less about abolishing slavery. It was all about railroad money.
It was about Railroad money, it was about Shipping money, it was about manufacturing money, it was about government revenue money, It was about banking, warehousing, insurance, and trade. About the only thing it wasn't about was freedom for the slaves.
It didn't become about that until the bloodshed had become so bad that revenge became a greater motivation than greed.
Yes, Lincoln was a corporate attorney with a "Mercantilist" ideology. What was good for big business was good for America.
We are currently fighting the descendants of these very same people in regards to illegal immigrants, and H-1B visas. Apparently the power barons have never quite lost their appetite for slaves.
Money alone was not justification for war.
That's why in his Inaugural Address on March 4, 1861 Lincoln told secessionists they could not have a war unless they themselves started it.
Which they soon did.
Why are you so intent to confuse yourselves on these matters?
