I mean, the literature is out there and it seems crazy to me that you’re pretending to have never seen a well-sourced article about wealth inequality and rent seeking, but here:

Trends in wealth inequality - https://apps.urban.org/features/wealth-inequality-charts/

Rich kids stay rich, poor kids stay poor - https://fivethirtyeight.com/features/rich-kids-stay-rich-poo...

How rent seeking is at the heart of America’s economic troubles - https://jpia.princeton.edu/news/something-nothing-how-growin...

I could go on there’s about a million articles about this. I’m sure you’ll find something to criticize but at this point it’s like denying climate change.
