Why aren't financial reparations part of the solution needed?

The linked-to article at https://apnews.com/article/caribbean-netherlands-slavery-mar... says things like:

> “Slavery was a terrible period, and degrading acts were committed,” he said as he called for financial reparations to be spent on education, health and other public benefits. “We remained poor.”

> Irma Hoever, a 73-year-old retired civil servant who lives in the capital, Paramaribo, said that the Dutch “do not understand what they have done to us.”

> “They still enjoy what their ancestors did to this day. We still suffer. Reparations are needed,” she said.

and:

> Activists in the Dutch Caribbean territory of St. Maarten have rejected the anticipated apology and demanded reparations, too.
