People have different levels of wealth and standards of living.
I was born into a comfortable business owner’s family.
I’ve lived through boom and bust.
I give my share, and more, or Tzedakah.
That said, I usually find that people who question what I spend on cars, clothes, my home and its amenities are just plain jealous. They may express it in terms of ‘he could be giving more to help others, if he drove a Chevrolet instead of a Jaguar’ but it is their jealousy showing through.
We are not Essenes of biblical times choosing to live a life of voluntary poverty and deprivation.
If there are those in my neighborhood who lack what to eat, I am more than happy to help feed them, to help educate their children and to help them find employment so that they can provide for themselves. That doesn’t mean I should have to do without things I can afford.
That said it is never appropriate to show off. The discussions of the ‘over the top’ vacations, and vehicles are a sign of the nouveau riche. Established wealth is discreet and not showy.
