Only 5% of all slaves brought to the Americas came to the US. The other 95% went to Central America South America and the Caribbean. Why do the blacks in those places never cry for reparations?
Answer: No liberals pushing their racist agenda.
And Spanish cultures continued to practice both slavery and Peonage (another form of slavery) long after your Civil War.
In fact, the last peonage slaves in the United States were freed in New Mexico in 1966 — the slaves were natives held by rich Spanish families.
