I think you’re right, in that reparations are going to be a tough sell as long as we’ve got such inequity in distribution of the wealth and resources of this world. I point to what I think it a wholly inaccurate term when it comes to economics but is widely accepted: redistribution. I propose the term we should be focused on is what is Correct Distribution. In that light, reparations are a rebalancing for what should have been.
I took a stab at it here: Reaching an Understanding on Reparations.
