And lest you think it’s me who makes such statements, having not been anywhere near rich at any point in my life, i direct you to a sefer called kohelea, written by the most powerful, richest and wisest man to ever walk this world. Rashi says this is why Shlomo hamelech wrote this sefer, decrying gashmius, because he understood wealth and was in a position to denounce taavah without being told he has sour grapes.
He doesn’t only denounce living beyond one’s means. Actually, i don’t think he does much at all – he decries going after taavos. Who told baalei batim this myth that taavos are ok as long as you wear fabric on your head, make blessings, (but don’t get too caught up in which brochos to make, because shehakol works for everything!) don’t talk about work on shabbos (unless it’s really really big business, then nisht oif shabbos geredt works) give tzedaka, you’re 100% a kosher jew and mezuman lechayei olam haba?
