OTOH, if a slave fights for the Confederacy and the Confederacy loses, any recompense which is given by the Union must still come through the system of private ownership of the land and commercial privilege which was perceived to be a white dominated arena.

Slave owners refused to allow valuable slaves to fight in a white cause under the mistaken belief that by denying legal precedent for service in a failing national entity and appeasing the enemy by engineering of Union victory, they would be protected as economically necessary members of the national economy.

Instead, Reconstructionism ruined them enmasse and what the North didn't take through illegal acts of Congress, the British did: chockablock replacing U.S. cotton with Egyptian equivalents as the dominant force in the cotton industry for the next 70+ years.

Still gathered by what amounts to slaves too.

The Civil War was a tragedy because the rise of mechanization and the depletion of Southern Soil would have made the end of the independent Cotton Barons lifestyle a given anyway. Whether slaves were repatriated home or became the founding members of a new form of indentured servitude in the Northern Industrial Revolution wouldn't matter as much as the lasting harm to our social cohesion caused by the various civil rights rent seeking abuses of the last half century.
