It's comparable to the US. If you look at the roster of billionaires in Germany, and then look at their national median wealth figures, it's stark.
Klause-Michel Kuehne scaled from Germany's economic size to the US economic size would go from $37b in wealth to $195b. That's Jeff Bezos.
Dieter Schwarz scaled similarly would go from $26b to $135b. That's Bill Gates.
Susanne Klatten scaled similarly would go from $24.6b to $128b. That's Zuckerberg.
Thomas and Andreas Struengmann scaled similarly would each go from $21b to $109b. That's Warren Buffett.
Stefan Quandt scaled similarly would go from $21b to $109b. That's Steve Ballmer.
And so on. Germany has 30 of the top 500 largest individual fortunes globally; the US has 159. Interestingly that's the approximately correct scaling if you account for the difference in economic size (although one would expect it to increase even further with scale, and given the US also has other things in its favor (eg global reserve currency, military superpower); so Germany is more than pulling its weight in relation to the number of US billionaires at the top). Overall Germany had 153 billionaires as recently as 2019, while the US had 788 that year; once again that scales roughly correctly for the difference in economy size.
So yes, the incredible wealth at the top in Germany is every bit as lopsided considering the size of the German economy.
Germany's median wealth figure is below the US. That's despite the US massively debasing its median with tens of millions of poor immigrants from Latin America over the past 40 years (meaning those people are starting from scratch, typically with no valuable labor skills or education background, and often without even knowing English). Comparing apples to apples, US demographics to Germany demographics, US white people are drastically richer than German white people at the median. And it's also despite the US not having the much vaunted labor protection that the Germans enjoy.
Germany, given its immense economic output, relatively stable culture and politics, high productivity, and strong labor protection, should have extraordinary wealth at the median. It doesn't (France and Britain both far exceed Germany in that regard; Germany is only slightly ahead of Portugal by comparison).
