What do you think? This country was built off free labor from African slaves. Why should that work not be compensated?
Slave labor =/= free labor. Black slaves received free housing, food, clothing and health care. All of these provisions carried a cost for slave and plantation owners.
You seem totally unfamiliar with world history. Blacks enslaved blacks in Africa and still do. The Moors conquered Spain. The Mongols conquered Eastern Europe and made inroads into western Europe.
Blacks and Indians also owned slaves in the US.
By your standards, Muslims and Mongolians owe whites reparations. Blacks and Indians owe reparations today to people who have never been enslaved.
