Matt Bruenig at People's Policy Project posted a pretty staggering chart illustrating the difference in changes to net wealth between the top 1% of Americans and the bottom 50% over the interval 1989-2018. I grabbed the same data and plotted each category, starting with the above, "Net worth".
The rich are getting a lot richer, and the bottom half of the country is treading water (at best).
More charts below. The Fed also provides its own interactive visualizations.
