Religious Folk are Biggest Givers

From "Cheap in America," a special 20/20 aired on ABC Wednesday:

20/20's John Stossel: The single biggest predictor of whether someone will be charitable is their religious participation.

Religious people are more likely to give to charity, and when they give, they give more money: four times as much. And Arthur Brooks [author of the book Who Really Cares] told me that giving goes beyond their own religious organization:

"Actually, the truth is that they're giving to more than their churches," he says. "The religious Americans are more likely to give to every kind of cause and charity, including explicitly non-religious charities."

To ponder:
1) Why do you think religious people tend to be more charitable?

2) What motivates you to be charitable? Are your motivations different when you do volunteer work than when you give money or goods?

3) What do you think are the biggest obstacles to being charitable?
