> you can't take it with you (at least in most religions) so spend it.

I don't understand this PoV at all.

I can't take it with me, sure, but I'm happy anyway if I leave it behind to my kids.

This PoV that you need to spend, spend, spend to get the most value for your money is very primitive - my kids will do better if I die before touching my nest egg, and if I don't at least I'll have a longer runway to live without working.

There is no downside here, other than the artificial one that dictates you spend it all and leave nothing behind.
