Anything above or below IQ = 100 is unfair by the very definition of IQ. But I understand the sentiment, I'd also feel cheated by the universe if I were born with below-average IQ.
The debate over fairness/unfairness seems to me like another example of the typical trap humans fall into - instead of bickering over who gets more of the pie, we should be focusing on increasing the size of that pie. If all the effort put in the discussions about meritocracy would be put towards intelligence augmentation, we'd have a world better for everyone, regardless of what gene he or she got.
