I agree with you, but african americans have had a unique situation in the USA. I am not categorically against slave reparations, if it's approached in a wise way.
This plan is a great political maneuver - it is (rightfully) limited to descendants of slaves (not all black americans), and the benefit is as great as the work output the person creates.
This also puts the dems in a bind.
Are the descendants of slaves worse off than the overall black population?
If you're so intent on getting reparations for descendants of slaves, contact those Africans who SOLD them into slavery.
