REPARATIONS [% of GDP] ?, page-48

What about all the money, resources & services they have received free of charge for the last 200 years?
Or the $30bn a year they already receive?
You're dreaming.

As a point of reference look at the only treaty signed in the last 50 years, Noongar in SW WA.
It works out at about $26,000 per person over 12 years (not each year), plus housing.
That's it, not in perpetuity after 12 years it's over.

A % of GDP in perpetuity will never happen.
