Cheap in America?

Did anyone catch Wednesday night’s 20/20 report “Cheap in America”? It was by John Stossel on charitable giving. I learned some interesting observations:
1-Conservatives give more than Liberals
2-Religious people give 4 times more than non-Religious (even to non religious charities)
3-The US Government ranks lower than many other governments in aid, yet our citizens’ personal giving is much higher than citizens from other countries.Links to the stories:
