Submission statement b/c I know Mother Jones gets pilloried as a source by some on here:

This article is a thought-provoking piece that compares today's American billionaires (many of whom have made their fortunes in tech) to the Russian oligarchs that came about post-USSR and the former US uses of the term in the pre Civil War and Gilded Age.

It's an interesting thought piece and speaks well towards how the current class of US ultra-rich got there, and spend their wealth on passion projects and chosen philanthropic endeavors while contributing to the squeeze on the lower and middle class citizens mainly due to our tax code taxing on income and not wealth, and the loopholes that allow them to pay taxes as desired.
