I didn't say "peers" (plural). I said "peer." It's one thing to take your peers as a whole and say you're better than them (and I'd agree that, by definition, if most people make that determination, they're wrong), but a very different thing to take a single peer and believe that you're better. You may still be wrong, but it's easier to semi-objectively evaluate differences between your skills and a single other person's.
Of course everyone is biased to some extent, but the bottom line is that some people will correctly assess as skills difference. If you have 10 people of varying ability (even only slightly varying), all making the same amount, 5 of them will be equal or better than the average of all of them.
