Let me point out, thought that the United States also spends billions more than any other nation in the world in helping other countries.
Does this mean that charity IS THE American way?

Not necessarily Amos, if you are speaking of US Government Aid to other poorer countries in the world, as far as industrialized nations go, the US, per capita based on GNP, is actually at the bottom of the heap.
But as far as donations to NGOs are concerned, I wouldn't be surprized if the Americans, as individuals, are not the most charitable.
