It’s been 20+ generations since slavery.
My secretary and her family were evacuated from their farm in Florin south east of Sacramento and spent the war in Manzanar. Their farm was sold to some white folks by the government.
When they got reparations i think in the late 80s she, her mother and her husband who was at Tule lake, each got 30,000. The reparations went to those who were in the camps and still alive when the reparations were paid.
The value of the land and development of her family farm at the time, 1.7 million.
A generation is 30 years, so that would be 600 years....
