Judging by what I read here in the QA, a lot of people have a sort of "I've got mine, so to hell with the rest of you" attitude. There is no sense of obligation to contribute to one's society or community, and there seems to be no desire to help those who are less fortunate or in need.
Strangely, my parents, who both lived through the Depression, had the same attitudes. They resisted any sort of charitable work or giving. I understand having that attitude when you have nothing, but when things are better, I don't know why anyone would ever want another to endure the same.
