@ahornsirup definitely. In some cases the perpetrators continued to extract throughout their lives. (And beyond, in Haiti: the former slaves had to pay reparations to France for freeing themselves for generations).
But, reparations are not about punishment of perpetrators.
Reparations are normally about stopping the people who are currently having to pay for the past, from paying for it.
This is done by redistributing some of the profit from those who are currently profiting from the past.
