Sometimes the world's biggest issues can seem so intractable that meaningful change feels impossible. But what if the answer has been right in front of us all along? What if the answer is actually throwing money at the problems? In this thought-provoking talk, philanthropic advisor Natalie Cargill shares what might happen if we came together to spend 3.5 trillion dollars on fixing the world. And, yes, she also has a plan for where to get the money from. (Followed by a Q&A with Anna Verghese, executive director of The Audacious Project.) After the talk and Q&A, Modupe shares her philosophy on giving.
