That site is weird. As far as I can tell, it's measuring income inequality, not wealth inequality, and it doesn't... appear to know the difference? Quoting it:
> The Gini index, or Gini coefficient, is a statistical measure of wealth distribution developed by the Italian statistician Corrado Gini. The Gini index is used to gauge economic inequality by measuring income distribution, also called wealth distribution.
It's a kinda big red flag if they say that income and wealth are the same thing!
There are a few notable cases of European countries having very high wealth inequality despite lower income inequality (my take which may not be shared by many: having low income inequality makes it hard for people who aren't generationally wealthy to overcome old money). Notably, Sweden has a higher wealth inequality than the United States.
However, I don't think it's true that Europe in general has higher wealth inequality than the United States. Here's the wikipedia list: https://en.wikipedia.org/wiki/List_of_sovereign_states_by_we...
