I sense you think like dante, in the sense that you think wisdom has to do with how much money one has, someones career, or thier social status. That's a twisted ideal born of society.
I don't know other peoples definition of wisdom on here, but imo wisdom is about recognizing ones own ignorance; the fact that we know few things, but are ignorant of many.
Socrates (far from rich/no career) dismissed notions from others claiming he was 'the wisest person', because of the fact he claimed (and knew) he knew jack shit. Yet people regard him as a genius, and it had nothing to do with his social conditions. It is all in the mind.
"Thinking we know, when we do not; is the minds worst disease. To know, and yet think we do not, is the highest attainment."
