Short answer - I can think of dozens of examples where it has been evolutionary advantageous to provide equal access of each individual to the resources of the group. Ants and bees come to mind first, Meerkats, slime molds, and of course primates. By definition, primates are social creatures, the conceptual framework of "equal opportunity" has its limits of course, it's typically read: "equal opportunity for one's tribe". Regardless, we evolved (over the last 10 or so million years) in a largely cooperative framework, where sharing of resources, division of labor, etc. are fundamental aspects of human nature. Those Australopithicenes in Olduvai Gorge were not lone individuals out there, they appear to have worked together with at least some division of labor, for the good of their group. The way the tools look and are shaped indicate amounts of time where only an individual who had access to substantial food resources, could have made them.
In short the evidence suggests that we evolved tool use, culture, and the social structures that circumscribe "humanity" as adaptations to survive and continue moving forward, not in spite of them.
But, for what it's worth, the evolution of sociality and cooperation is indeed a perplexing one, because it is counter-intuitive to the general premise of natural selection and thus it has had thousands of pages of text and millions of hours given to it. It turns out that many systems have evolved degrees of cooperation or shared interdependence (remember, we even have a term for it, symbiosis). But we do see that after awhile these systems will break down, greed is inevitable. As it turns out, greed is what always destroys cooperative systems. If you want a justification for embracing "equal opportunity", it's because without some degree of cooperation, the system that is humanity will break down. It may come back, but it will be on a timescale that suggests that it will be dozens or hundreds of generations downstream before it does. So, if you value your species...-at least think about-*.
*By the by, I don't think this will happen fast. But based on studies of extinct systems, one aspect we see consistently is that each little break down of aspects of the ecosystem destabilizes it, until only a moderate push sends it over the edge and spiraling down into oblivion.
