For simplicity's sake, say you live on a world with exactly one other person. Between you both, 100% of all resources are allocated, but the other person has 100x the resources you do. Please explain how you would achieve equality by raising your resource level to match the other guy's. Technology enabling exploiting of new resources is not really an answer to the question, since developing that technology requires use of current resources, which means 100x the technology is available to the other guy.
