Thanks for posting that....very interesting. Do you know if they normed everything to “todays dollars” - meaning was George Washington worth 525 million back then (that would be zillions today) - or is that 525M grossed up in todays dollars?
It HAS to be adjusted dollars.
Those numbers for sure have been converted into today's dollars, maybe using a time series of "average" prices in the economy -- that is, via some kind of standard price index like the CPI.
On the other hand, if the article had valued GW's real property in Fairfax County, Virginia (ca. 7000 acres) at today's FFX County real estate prices, he might outrank Warren Buffet, Bill Gates and the Sultan of Brunei! (And beyond GW's FFX County holdings, I guess one should add today's real estate value for the thousands of acres the venerable old surveyor and master speculator had bought in western Virginia, Pennsylvania and the Ohio country.)
