A more effective persppective I think:Ask not what THEY do (or do not do), or define that which you think THEY should do.
YOU (generic) do what YOU can do and maybe that will inspire people to join with you.
And BTW, in three years of association with Red Cross, our tiny, poor area raised a LOT of money for overseas disasters. More than was given spontaneously for local disasters, and we had them. People give far more than I think you have realized, and have done so, for years.
Judging how people feel and how much they care and how much they give, by what you see on TV, is just silly.
