Having read the rest of the comments I would like to amend my definition as being the definition of "rich enough." Certainly I would never actually describe myself as rich. But the answer to "do I need to be making more money than I am now" is no. Certainly, sometimes I get low on cash; now is one of those times, I'm about to spend a week in Amsterdam and Spain and I just bought one of my plane tickets to the States for Sister #2's wedding. I DO have more money, it's just in savings. Having money you have hidden away does not equate to not having money.

I think your definition is more what I think of as "independently wealthy". It relies on not having to work versus what income you derive from your work.

Also, my income would be pathetic if I were trying to support my partner and/or some kids on it. For just me it's plenty.
