How can society effectively eradicate complex social problems like poverty and hunger, racial injustice, human trafficking, and the opioid addiction crisis? Baroness Philippa Stroud, CEO of the Legatum Institute and a Member of Parliament in the United Kingdom, and UVA Professor Lucy Bassett discuss how to confront social challenges through different organizational systems, and the levers that lead to effective social change. From grassroots organizing to legislative and policy changes, Stroud and Bassett explore how it takes the collective work of multiple systems — including government, think tanks, nonprofits, and businesses — to create meaningful, long-term change.
