Answer by Jimmy Wales:
To really understand my answer, get a copy of "" and read it.
By any sane standard of measurement, yes, of course I'm rich. Nearly half of the people on earth live on less than $2 a day. I spend more than that on my cellphone bill. About 80% of the people on earth live on less than $10 a day.
But the point I'm making is that people often get sucked into a way of thinking about things that makes them think that a reasonable standard for measuring whether someone is wealthy or not is appropriately measured relative to Mark Zuckerberg or the Google guys or whatever.
But there's another angle to this, and that is to ask what "wealth" means. People who equate wealth in any serious way with "amount of money that you have" are missing a lot of richness in how humans value things.
What I think people most value (or ought to most value) is rich and interesting life experiences. On that level, there is no doubt that I'm rich, and much richer than one might imagine from my relatively meagre (compared to billionaires!) financial resources. As I've mentioned in another Quora answer somewhere, there are car dealers in random Midwestern towns in the US who have vastly more money than I do. But they have nothing like my quality of life as measured by interesting experiences.
So, my final answer is: yes, I'm rich. But not in the way most people think about the question.
