In terms of assets? Liquid cash? Annual disposable income?
If you think of someone as wealthy, what number does that mean to you?
What number would cause you to think of yourself as rich, or wealthy?
I've known people who make half a million per year who think of themselves as part of the middle class.
I've known folks who made big windfalls (usually inheritance), but quickly spent it all.
I'm looking for more hard numbers than anything, but answer the question in any way you want, of course.
