Sadly, there is simply no way to fashion a reparations remedy that would not, itself, do an injustice to people completely undeserving of that harm, as if a fair value could even be sorted out. Two wrongs will never make a right.
A crime requires a bad intent and a harmful act. That intention is not inheritable by descendants of slavers. Similarly, causation is not an inheritable trait by distant descendants of original victims.
So long as reparations remain the only end point for this “righteous struggle,” the struggle will have no end.
