The Democrats, NY Times, and other leftists want to raise the issue of who benefited from slavery, and how much.
Sailer points out that it is doubtful that whites benefited from slavery, before the Civil War.
The Civil War surely wiped out any benefits. And the costs of the slave trade continue to be paid by Whites.
On the other hand, African-Americans were surely the biggest beneficiaries. American blacks are the richest blacks in the world. Being a slave in America was surely better than being a slave in Africa.
I am not trying to justify slavery, as I don't think that it was even a net benefit for White people. The whole thing was a big mistake. But if someone wants to go back and revisit the issue of who benefited economically, you would have to conclude that the African-Americans were the beneficiaries.
Maybe I am wrong, and some commission on slavery reparations will calculate all the costs and benefits of the slave trade. I hope that they look at what would have happened if the Africans had been left in Africa.
