I believe this is an issue of scale: humans need to operate at a smaller scale for fairness to exist at all. We do not have any evolutionary preparation for operating collectively at global scale. Our small minds try to take advantage of our situation when in positions of power, while being incapable of realizing the mass unfairness that behavior actualizes.

This is an issue with human nature itself. We have to change our innate nature, and we all know... that is not going to happen.
