How would making states, towns or neighborhoods look richer cause outrage? For income statistics, median us a much better measure in most cases, because it reflects “the average experience” much better. If you want to highlight income inequality, there’s plenty of other stats you can use, e.g. the percentage of all income going to the top 1%.
Glad you already learned this is probably nonsense. The wrong reasoning is very similar to much thought about overpopulation. The amount of people that makes for a place to be overpopulated is a function of how societies work and the technologies they have at hand. One extra issue there is that improvements in technology usually lead to population growth, so much progress gets cancelled out.
