The poster has made a specious claim. There were actually no northern “power brokers” and the few “investors” one can find are very limited and mostly from IL., although one does stand out- Chief Justice John Marshall did fund the some of the southern slave traders, but he was a Virginian and prob did so to increase his influence. A true politician.
(Marshall, interestingly, was responsible for the Marbury decision, which allowed the SC to jump its Constitutional limitations re: jurisdiction, and lets them decide which cases are within their purview. Cultural “change agents” have used this to its full extent, i.e. Roe)
ALL the financial gain was held by the sellers and owners of slaves, one of the biggest plantation owners was a black man named Anthony Johnson, but his wealth didn’t come just from his plantation’s crop yields- they came from his practice of “breeding” his slaves for sale.
The determination to hold on to this wealth was one of the biggest factors in the Civil War.
The North controlled completely all of the Southern cotton trade with Europe. You probably didn't know that.
The Navigation act of 1817 gave the Northern shipping industry a virtual monopoly on all Southern trade with Europe, and they set their prices such that it was just below the cost of paying all the fines and penalties for violating the navigation act of 1817.
Because of the law, they had a captive market, and they could charge what they wanted, and of course they maximized their own profits.
Additionally, most of the money collected in tariffs, (72% of which was the result of Southern exports to Europe) was spent to subsidize Northern industries, as well as to build Northern infrastructure, such as canals and railroads.
The determination to hold on to this wealth was one of the biggest factors in the Civil War.
The Wealth was all in the North my dear. 4 to 5 times the population, and virtually all the control over shipping, banking, insurance, warehousing, and the congress.
Did it never occur to you to think it odd when the Northern controlled congress voted in March of 1861 for a constitutional amendment to make slavery permanent in the United States?
Why would a supposedly anti-slavery party like the Republicans vote *FOR* a pro-slavery amendment?
Well because they were more concerned about the continuation of that money stream than they were about any moral concerns over slavery.
You've been indoctrinated in the usual history. You will find lots of support swimming with the stream, but not so much if you swim against it.
