Jws like to jump between the old and new testaments, to cherry pick whatever thought they are trying to justify at that moment. Proverbs 13:22 is a scripture I haven't heard quoted much though. It explicitly defines a good person as someone that leaves wealth to their grandchildren.
This one, short scripture actually contains a lot of wisdom if followed. It encourages someone to think long term about other people's benefit and promotes a sense of responsibility towards money and wealth.
Contrast this with the ex missionary / pioneer elder I knew that passed away recently in his 90s. When I gave my condolences, his daughter told me, almost proudly, that her father had nothing and died poor. It wasn't the time or place to tell her that he died pooe because he expected the end to be here decades ago and he didn't save to help his children, but I was thinking it.
