Random point to share: there are natural generalizations of the Gini index that serve to capture tiered power-law dynamics, and can, in theory, be used to analytically capture the disparities you mention above.

I particularly like this article [Splitting the Gini Index in Two]( https://www.maa.org/sites/default/files/pdf/upload_library/2/Jantzen-2013.pdf) about quantifying the low and high tails of a power-law distribution to create a more realistic model. It’s striking to see how differently their two coefficients (instead of 1) change over time to give credence to “the rich get richer”.
