You're mostly misrepresenting U.S. civil war history. "The first panel of Figure 9 documents the extraordinary wealth losses in the South associated with the war. Up to the 65th percentile of the national wealth distribution, nonslaveholding Southern households held around 50 log points less wealth by 1870 than similarly wealthy northern counterparts. Thereafter, losses increased in a log-linear fashion, maximized at 95 log points for households above the 95th percentile. These wealth losses primarily reflect large declines in Southern agricultural productivity, reflected in the price of land. Wealth losses were even larger for likely slaveholders in the South, maximized in the 95th percentile at 130 log points." https://www.nber.org/system/files/working_papers/w25700/w25700.pdf True "by 1866, the

window of opportunity for land reform had closed and most Southerners retained their land after

the war"; however, the more important issue is overall wealth, which includes land, and white southerners did lose a significant amount of land too, which is why overall white southerners lost tons of wealth, a hit that lasted for generations.
