> When I look at that list, Jeff Bezos is #1. The first woman on the list is at #10 and inherited her wealth. Are you looking at a different list?

I think the comment does refer to Jeff Bezos. Here is the relevant section from Wikipedia:

"At the time of his birth, his mother was a 17-year-old high school student and his father was 19.[17] After completing high school despite challenging conditions, Jacklyn attended night school while bringing baby Jeff along.[18]"

IMO a 17 year old attending night school is pretty low in terms of economic status.

Also I am sure there are other cases but I know about #17 (Mukesh Ambani) and his father was a petrol bunk attendant - pretty low down even by Indian standards.
