Matt and Dara are joined by Vox's German Lopez to talk about the Biden administration’s plan to authorize third doses of the vaccine for Americans beginning in September. They discuss the scientific, political, and moral reasons behind the decision. They also look at the international implications of sharing vaccines and the difficulties of ramping up production in the vaccine supply chain ecosystem. This week’s white paper is a study of how slave-owning southern families retained their wealth and influence after the Civil War. The conversation illuminates the importance of social ties to political continuity and explores a similar study of Chinese generational wealth spanning the Maoist revolution.
