I have an ancestors who was owed money from the king of England for a loan made in the 1700s. The bank handling the account said that the money had to be evenly divided among the descends. What started out as a literal kings ransom got down to under $10 when divided evenly.

The original slavey reparations was an acre of land and a mule. Divided equally, even assuming multiple slave ancestors, would be a few square feet and just enough mule hair to make brush. Reparations done on the scale of harm done equally divided would be insulting. Making things better for everyone is a much easier sell.
