Bono described the moment in 1985 that changed his life — when a father in Ethiopia begged him to take his son, saying the boy would surely die otherwise. Twenty years after Live Aid, Bono told the graduates he was no longer interested in charity but in justice. Seven thousand Africans were dying every day of preventable, treatable diseases, and calling it a 'cause' sanitized the horror. He made the economic argument too: ending extreme poverty would be cheaper than the Marshall Plan and cheaper than fighting endless waves of terrorism's new recruits.
