Any system that allows humans agency will end up with a Pareto-style distribution in that thing (non-linear). Doesn’t matter if it’s wealth, HN upvotes, Crime, Traffic accidents, Productivity, Tetris scores, academic papers published, etc.<p>As for the slight drift in US wealth distribution since 1980, it’s wholly explained by the change in age demographics. Since 1980 we’ve gone from a nation of people 30 years old to 40 years old. 10 years is a lot of time when it comes to compounding returns on productive assets (stocks, etc). Due to compounding, wealth held by each age group also gets more Pareto-extreme heading into retirement age.<p>Adjust that out, and this is mostly a nothing burger. But emotionally people don’t feel that way so nothing I say will change that. Narrative zeitgeist always wins over objective reality.<p>Average Americans are wealthier than they've ever been. Another chart to drive this home, the percentage of Americans who have a passport since 1989 (Note, this is also influenced by age demographics, but not as dramatically as wealth): <a href="https://www.statista.com/statistics/804430/us-citzens-owning-a-passport/" rel="nofollow">https://www.statista.com/statistics/804430/us-citzens-owning...</a>
