Policy Punchline

What does the history of the dollar reveal about power, sovereignty, and the way money really works? In this episode of Policy Punchline, Financial Times journalist and Princeton historian Brendan Greeley joins Princeton students Alice McCarthy ’27 and Maddie Feldman ’27 to discuss his forthcoming book, The Almighty Dollar: 500 Years of the World’s Most Powerful Money. Greeley challenges the familiar story that the dollar began as an American invention. Instead, he traces its origins through Spanish silver, German mining towns, colonial ledgers, promissory notes, banking panics, and the private systems of credit that long preceded the modern Federal Reserve. The conversation explores why there is no single “dollar,” how different forms of money serve different people, and why monetary sovereignty is often far messier than governments or economists suggest. The discussion then turns to the present: crypto, stablecoins, America’s broken payments infrastructure, and the uncertain future of dollar dominance. Greeley argues that many supposedly new financial innovations are better understood as old banking problems in new packaging, and that the durability of the dollar depends not only on American power, but on the institutions, regulations, and trust that make money work. This interview is part of the Policy Punchline podcast series. Supported by Princeton’s Julis-Rabinowitz Center for Public Policy and Finance, the series aims to foster dialogue on critical public-policy issues, connecting listeners with leading experts from around the world. Join us as Brendan Greeley offers a sweeping and often surprising account of the dollar’s past, and what it can teach us about money, markets, and power today.

What does it take to repair a democracy from the inside? In this episode of Policy Punchline, Princeton neuroscientist and NJ-12 candidate Sam Wang joins Princeton students Maddie Feldman ’27 and Alice McCarthy ’27 to discuss his unusual path from brain science to election reform. Wang reflects on the common thread running through his work: using evidence to understand systems that shape people’s lives, whether in the brain, the ballot box, or Congress. The conversation begins with his research on neuroscience and autism before turning to his work founding the Princeton Gerrymandering Project, where he has used data, law, and statistical analysis to challenge distorted electoral maps and defend fair representation. Wang also discusses his run for Congress in New Jersey’s 12th District. We discuss New Jersey’s political system, including Wang’s role as an expert witness in the lawsuit that helped dismantle the state’s county line ballot system.

Join us as Sam Wang offers a scientist’s lens on American democracy, and a reformer’s blueprint for how to fix it.
