Completely dysfunctional state that would undermine everything the South actually wanted. The Confederacy, while mainly on the basis of slavery, also simply believed in the right for the culturally distinct South to pursue its own destiny.
While it may not have been the goal of the slave owners, a lot of the Southern intelligentsia wanted to basically break economic reliance on the North, industrialize at a slower but sustainable rate, and keep a rigid segregation between races. There's a really good book on this called Modernizing a Slave Economy written by a Pollack.
They'd limit immigration, even from Catholic Europe, and maintain a smaller WASP society based on very clear religious values (constitution had seperation of church and state, but also changed "endowed by their creator" to a mention of the Lord.) It would be a weaker backwater state, but a culturally rich one that maintains its traditions.
Now imagine this; they conquer all of Mexico, which will outpopulate it eventually. Cuba or Hispanola could maybe be effective colonies e la Hawaii or the Phillippenes, but all of fucking Central America? They have enougn issue keeping the blacks in check, now they'd be majority Catholic. The mestizos encouraged to move to the slowly industrializing North for jobs as the rest is kept structurally poor. So imagine Southern Texas but all the way across the entire South, and a lot more black people. If it somehow survived, it'd be a shithole, and the U.S. would be a pan-European (probably majority Catholic) state witj a lot of Asians in the West.
Laughable and retarded fucking scenario. Smaller South is more interesting.
