Wolf, you’re being disingenuous. There is a difference between spending like a prince and being a prince (or princess). There is that old-fashioned happy medium, the shvil hazahav. Not a miser, and not a spendthrift.
There are luxuries and then there are luxuries. A hidur mitzvah is not the same as extravagance. Enjoying your hard-earned money is not the same as throwing it in other people’s faces to get some kavod – or to prove to yourself that you “deserve the best” when you maybe feel a little doubtful about yourself.
Moderation, common sense, all those old-fashioned midos/virtues….
