The idea of the Confederates was that they'd already seceded. If they won the war, they'd be an independent country. After people had died, they weren't going to say that they hadn't seceded.
Whether or not the Confederacy, if it did secede, would have devolved into a corrupt over-centralized government is anyone’s guess, but you have no reason to assume they would have.
I say that because some people think that the Confederate government was a bunch of guys sitting around in a garage complaining about the government. No. They were a government (or wanted to be considered a government). They were an elite. They were used to having power and wanted to have more.
It's likely that victorious Confederate leaders would make use of as much power as they could get once they became independent. That might not have happened right after the war, but over the course of years, decades, centuries -- does anybody seriously think that the CSA wouldn't have problems as bad as we do now in the USA?
It seems almost to be a law of history that revolutionary leaders complain about the power of a faraway government and then when they get power themselves they use as much of it as they can -- even more than those they overthrew did. It may not be inevitable and a law, but it's a good bet.
FWIW: You got some strange ideas about 19th century America. I don't know what price controls you're talking about, but slavery really was a very big issue.
Well, your version of history is far more common than mine, I’ll grant you that.
Do you think the nearly universal acceptance of your views might possibly have something to do with the fact that it is the only point of view taught in schools?
The North won, they get to write the history in a self serving way. It was all the fault of the South’s perverse love of enslaving people. Thank god for the North putting an end to it.
Think what you want. You’re certainly in good company.
