To me, the OP’s post is an inquiry into “why” we do what we do. It is a useful inquiry that may be followed up with personal introspection, which might lead to a better understanding of ourselves if done with integrity.
For example - we work to earn money. Why do we earn money? So we can live comfortably (your answer might vary). Why do we want to live comfortably? And so on…
The line of reasoning you seem to have chosen ends at “to earn money” and then pivots to philosophers being affluent while seemingly (to me) proceeding to dismiss all the learnings procured by affluent people as though that makes them inherently different to the learnings procured by others (a conclusion that seems to have no solid basis).
