I'm not sure what you mean by "self-redistribution". I at first assumed you meant economic "market forces" as opposed to government intervention. If that's true, then those market forces are almost entirely rich-get-richer. Sure, there's the "creative destruction" as some fortunes are lost, but that's actually part of the driving force for inequality -- that's what forces capital-owners to seek growth as opposed to allowing them to stay static.
