אמר ליה שמואל לרב יהודה שיננא חטוף ואכול חטוף ואישתי דעלמא דאזלינן מיניה כהלולא דמי
רש”י
חטוף אכול – אם יש לך ממון להנות עצמך אל תמתין עד למחר שמא תמות ושוב אין לך הנאה:
כהלולא דמי – היום ישנו ולמחר איננו דומה לחופה שהולכת מהר:
This is brand new Hashkafa, that your money is not yours. Yes, there are Mitzvos to do with your money. I’m sure that a Yid with a חזקת כשרות did those Mitzvos. Telling someone he should have given money away, just because he spent it on himself, shows an attitude akin to the Wallstreet protesters. No, this person got ברכת השם and he isn’t stingy but is able to spend it to his benefit.
If you want someone to give Tzedaka and feel that he can afford it, speak Divrei Chizuk, convince him of the cause, and realize that he doesn’t owe you anything.
And now traveling to an interesting vacation became the mark of gluttony? No, bantering on how others could have spent their own money is the mark of jealousy. Calm down. It’s only עולם הזה.
