As far as "that family," I don't know them. Perhaps you can tell us a bit more about them from a hands on perspective?
Regarding those I know 1st hand and work with where I work, not a few get on with 20K/yr + or -. Not infrequently, less than that.
Back to the point at hand, when giving someone something to eat vies with holding onto a few bucks that mean little or nothing to us, the choice should be easy.
But that's not the issue either, and I'm not talking about government programs, taxes, etc. If you don't know what I'm talking about just chalk it up to "he's a nutty tard."
It's a Matthew 25 sort of thing. And not a bad day to mention it, being Holy Saturday, and tomorrow being Easter Sunday.
I have taken more out of life than I have given. Many people I know first hand have done the same. There are those, too, whom I know first hand, who set a better example, who seek actively ways to better their neighbour becuase its merciful to do so. They, by in large, see everything they have in life as a "gift." Not the more common point of view that "I deserve it because I earned it."
I don't think that if anyone gave a thoughful and serious assessment to the question "do I deserve all the good that has come my way" if that has been their lot that they will answer "yes." When those times arise and friendships favor frankness, I have heard in some detail how they and their "good lives" are the product of sacrifices that others have made, be it parent, relatives, friends, teachers, etc. The list can and should be pretty long.
It is a narrow, bleak, blind-hearted life that seeks only or mainly to hold onto all that is "theirs" without some efforts to assuage the hardships of others that they find nearby.
I'm a poor example on that score, and I hope that I shall improve.
