Development aid - help or hindrance?

Celebrities have made foreign aid cool. With their themed wristbands, tireless campaigning and regular trips to Africa, people such as Bono are among the world's most prominent activists.

The face of development aid has changed since Congress passed the Foreign Assistance Act in 1961. More and more famous people are signing up to "make poverty history" and save Africa from war, corruption and HIV/AIDS, and they are asking the U.S. and governments across the globe to give more to the cause.
