Miles away from what you seem to have understood. Re-read that statement, and make an effort to understand it. It is very simple really: Charlie Munger was admirable after his wisdom - intentionally and purposely built.
Incidentally, your (delirious and disconnected - I speak of Being, "Being" which is opposed to "having" after at least Fromm, and you are there attempting to adapt what I wrote into concepts of theft) process seems to fall into that bias that Charlie Munger insisted on, of having embraced some judgement so tightly that it blinds you.
Returning to what I expressed: people «not well off», in wisdom, they met somebody «way better», in wisdom - which is a core point in the «achievement» in question -, and through their own effort, facilitated by gifts, «take part of the wealth». With a collective gain.
My original reply was faithful to your question: "what did he do in life worth of admiration", to which you have been replied: "he built himself well". And he shared that achievement generously. Other matters like faults are contextual to different questions.
Being. Being well is an achievement.
What you come up to be is something you do - you develop it.
