I skewered that non-sequitur the moment I laid eyes on it. Hardly a great response. In fact I would characterize it as "not even a response".
The evidence of "follow the money" has yet to be refuted in any reasonable manner. Indeed, Charles Dickens noted that the War appeared to be over who was going to get the slave money.
…the Northern onslaught upon slavery is no more than a piece of specious humbug disguised to conceal its desire for economic control of the United States.…Union means so many millions a year lost to the South; secession means loss of the same millions to the North. The love of money is the root of this as many, many other evils. The quarrel between the North and South is, as it stands, solely a fiscal quarrel.
Oh, and lest you think he was some sort of Southern Sympathizer, he was adamantly anti-slavery. He just happened to be willing to tell the truth.
In 1842 Charles Dickens & his wife made their only visit to the US before Civil War (there was a second visit afterwards).
Apparently it was not a happy time for him, as he objected most strongly to the money-grubbing US capitalists who refused to honor his international copyrights, and published his very popular works without paying him.
Since then, Dickens didn't like Americans, North or South.
When it came to Civil War, much as Dickens didn't like slavery, what he didn't like even more were those money-grubbing Northerners who'd cheated him out of a nice profit.
So, of several possible motives Dickens could have ascribed to Americans (Union, secession, slavery, etc.) he chose the one that best matched his own previously held views of Americans: money.
In fact, Dickens had no special knowledge -- none, zero, nada -- of either US & Confederate leaders or their motives and so likely took his comments straight off pro-Confederate propaganda, such as your link here.
It suited his mood and avoided any need to take sides.
By the way, DiogenesLamp, if you admire Charles Dickens then you're in good company.
So did Karl Marx and George Bernard Shaw, heros of yours, aren't they?
