I actually was going to post pretty much what Dennis did this morning. I think unless my family member was a child molester or something, it would bother my conscience to have him living in abject poverty and danger when I have so much. Perhaps help him get an education so that he can improve his lot in life.
That's just me though, familial relationships and circumstances differ wildly so it is hard to project my view based on my family onto someone else and theirs, as Aaron illustrated. In mine blood is blood, and not cheap; others' mileage may vary due to circumstance.
