That's a factor of ten, which is like calling me a millionaire when I saved just enough to buy a 35 square meter apartment in a small village just outside Cambridge (UK)… in the middle of the house price dip from the global financial crisis.
Fair, I've heard the same from chatting with someone who shall not be named who got on a different list.
I can't remember if it was them or someone else who said that people lie about their wealth all the time for lists like these; the show-offs who want on them and pretend to have more, and the quiet ones who want off them and pretend to have less. (The person previously mentioned was one of the quiet ones).
