I think a combination of a small number of ideas is needed. One of those ideas happens to be "crazy" and will never happen - an amnesia of history and total loss of all its archives. Imagine future generations growing up with zero knowledge of history, or at least any pieces of it that could contribute to a growth of racism in the world. Would ignorance not be bliss in this case?
But even while I think we'd at least be temporarily rid of it, there's a chance it could return - for the same reasons it ever came to be in the first place.
