As another reference point, an annual salary for low-to-medium skilled labour in mid-17th century Holland was around 100 to 200 guilders, which would be about 20 million USD according to the implied "Infl. Adjusted" conversion in the article (upon which the entire premise of the article rests).
It does make you wonder what the inflation-adjusted figures are purported to mean even, given that they result in completely ridiculous results.
