I am not sure if this line of thought can lead to anything but frustration? The idea of fair would require a universe where we all come into existence with equal abilities and opportunities. This is not reality for our universe, everyone inherits different genetic advantages and disadvantages from their parents as well as being born into wildly different social environments that in turn afford difficulties and advantages.

Some aspects of our reality are difficult to accept. It gives me some comfort to imaging a universe where everything was equal (and consequently the same), such a universe would not produce the wild variance and spectacles of life that we have in our universe. It would be well...boring. In addition, such a universe could develop the same social advantages and disadvantages based purely on probabilities.
