What they did at the time was absolutely horrible. You're free but how free can you really when you need to keep food on the table and have never been taught any skills outside of your role as a slave? While they might have been granted freedom many, probably most, were not given the resources to truly act on that freedom.

That being said I think reparations at this point would ineffective and a politically infeasible. The money that would hypothetically be used for such a thing could be more effectively used providing services to low income areas.
