In an RBE the need for human work would be minimised by automation, and by ensuring that only what needs to be done to sustain life on this planet - especially human life - gets done. No work is created for people to do so they can "earn" the right to a share of the earth's resources.
A possible counter to this aim for ever decreasing work is that there is dignity in labour. Well, if that's true, people will labour to gain the dignity it imbues, and aren't only motivated by money. Freed from the drudgery of working to survive, people can find their true métier and work at that, if they wanted to. An RBE frees people up to do what they want to do.
