The “tails” of the distribution on the higher end of the income brackets, the extreme, are much more determined by changes in inequality than changes in the average. It gains from dispersion, hence is antifragile.

Some apartments, those for the very rich, sell for twenty times the average per square foot of a building a few blocks away.
