Uncorrectable as matter of physics? Or uncorrectable as a matter of American political will? If the former, sure, it's conceivably correctable. If the latter, Oi. The sin, in my mind (or rather in my mind at this moment), is the reverence we (continue to) give to the concept of the economy as wealth production (as opposed to service production), and thereby the sway we give to wealth-holders. Even, if we cared to take on the task of reparations, what does it look like, how does it begin? Cutting a check would wash our hands of it, and hardly solve the problem. (i.e. an augmented welfare, that wouldn't build sustainable much less inheritable/pass-onable skills). There's real geographic and community boundaries. We may not be able to terraform the reservation or gentrify urban centers; and more, we cannot better-shape how such people may see themselves, and buy-in to the supposed limits of their successes. An exceedingly difficult problem. It's shame we don't have academic programs devoted to it, instead of whatever drivel they've been hanging tenure on. (Forgive me, it's late, and I have opinions.)
