Because it’s not worth engaging with this person I just copy paste my answer to the other place where they posted this.
Thanks for linking a source but this is a misleading interpretation, please don’t try to argue with data if you don’t know how to interpret it.
You need to look at e.g. the top 10%, middle 40% and bottom 50% to get a proper idea. And then look at it country by country because the scales don’t match. Yes, the USA are extremely inequal, I think back to like 1913 level in 2013 or something like that iirc, so if you put them on a plot with e.g. France, France will look great.
But if you look at France alone you get a different picture and inequality is rising again since the 80s. Here’s an article by a French economist with research focus on inequality which cites the same data: https://blogs.lse.ac.uk/inequalities/2025/09/24/global-inequality-in-historical-perspective-part-1/




You obviously did not look at the data they used as source
