Do we have a duty to help the poor? How do we quantify that?

[Micawber]

The church and charity groups do not have the means to help all the poor of the world.

Dear StrictCatholicGirl,

I undesrstand where you are coming from; and it's laudable that you feel the way you do.  However, i beg you to please think about the following:  if indeed it's true that the "church and charity groups do not have the means to help all of the poor of the world," why do you think a government does?  Think about this carefully:  where does the government get its "means"?
