Why do people give—is it because they are magnanimous or because they feel guilty?

Does volunteerism discourage initiative and self-help and make those at the receiving end dependent on hand-outs?

Does it matter how a philanthropist makes his money so long as he/she gives it away?

Can giving and profit-making be combined?

Does it help—or hurt—to have rock stars and TV personalities (e.g., Bono, Shakira, Winfrey) get involved in discussions of poverty and other global challenges?
