master slave morality

Consider living in a world of imbeciles. They subsist but barely. A superior intellectual individual enters this world and manipulates it such that he no longer spends the majority of his time subsisting. In fact he organizes some of these imbeciles and builds wealth, only for himself but does increase (accidently) wealth for those he has used. In the sum of all things, some imbeciles have a better world wealth wise. We know this superman increased his lot proportionately more than those who helped, but if he was never born the wealth would not have been created.Do they have a better world morally? The imbeciles wonder why their life is so hard while the superman's is not. Jealousy is assured leading to hate, envy and folksy tales of why this superman is immoral. If we replace "superior intelligence" with some other factor x, is this not our world?
