I was able to find the estimated net worths for all 46 US presidents, from George Washington to Joe Biden. All of them have been adjusted to today’s numbers to keep things even.

Notably, many among the first 18 presidents acquired their wealth through land ownership, which was largely worked and made profitable by enslaved people, or an inheritance that included enslaved people.
