Here's the fed's up-to-date numbers. So yeah, that's a decent summary.
Doesn't it show exactly what I said? Lemmy has a whole lot of top 10% people - I wouldn't be shocked if it's the majority. Nobody here is thinking of them when they say "ruling class". The top 1% also contains a lot of kinda-rich people, who maybe own a couple of car dealerships, but could never afford a jet. If they do something in IT instead of cars, they again might be on Lemmy.
The total is about 170 trillion. For reference, Forbes billionaires, including the non-American ones, add up to 16.1 trillion.
