Overview of Freakonomics Radio episode 673, “What Is Money?”
This episode follows composer David Lang as he prepares a new New York Philharmonic oratorio, The Wealth of Nations, based on Adam Smith’s landmark 1776 book. Host Stephen Dubner uses the project as a springboard to explore a bigger question: what is money, really? The conversation blends music, economics, art, and social philosophy, arguing that money is not just a medium of exchange but a social construct that shapes how people relate to one another.
Main Themes and Ideas
Money as a social invention
Lang frames money as something that has value only because people collectively agree it does. He sees it less as a cold economic tool and more as a social lubricant that helps strangers cooperate, trade, and avoid violence.
Trade, labor, and interdependence
A key idea in both Adam Smith’s text and Lang’s music is that even simple objects—like a wool coat—depend on the labor of many people across many places. The episode emphasizes how modern life is built on invisible networks of cooperation.
Wealth, inequality, and moral responsibility
Lang is interested not just in markets, but in the moral question of how people live together. The piece draws on Smith, but also on Frederick Douglass and Eugene V. Debs to highlight inequality, exploitation, and the ethical limits of commerce.
Art as a way to make economics felt
Lang wants listeners to feel the emotional weight of trade and money, not just understand it intellectually. The oratorio uses repetition, choral writing, and layered text to turn economic ideas into something visceral and communal.
David Lang’s Creative Process
Why he chose The Wealth of Nations
Lang had previously succeeded with a similar project for the Philharmonic—reworking Beethoven’s Fidelio into Prisoner of the State—which led to the commission. He admitted he would never have read Smith’s book unless he had to, but once he did, he began searching for its emotional and thematic core.
From jokes to deeper meaning
At first, Lang imagined a playful parallel with Handel’s Messiah, even hunting for “sheep” references. That idea faded, and the piece became more serious: a meditation on trade, labor, enoughness, and the human meaning of money.
His style and working method
Lang describes himself as a composer who works from text, voice, and rough ideas on paper, not as a pianist-improviser. He likes embracing mistakes, avoids software that “corrects” too much, and prefers lowercase titles as a kind of anti-pretension gesture.
Broader Reflections on Music and Community
Classical music as “high prestige, low reach”
Lang argues that musicians have a duty to make great work accessible without dumbing it down. He wants a larger audience for contemporary music and has spent much of his career trying to widen who gets to hear and participate in it.
Bang on a Can and democratizing music
His early work with Bang on a Can was built around expanding experimental music beyond a small elite and encouraging a more generous, collaborative culture among composers and performers.
Crowd, democracy, and shared experience
One of Lang’s earlier community pieces, Crowd Out, was inspired by watching a soccer match where thousands of strangers participated in a collective experience. That idea—performance as a form of democracy—connects to his broader artistic philosophy.
Notable Insights
- “Money is a social construct.”
- “Enough is as good as a feast.” — a family saying that shaped Lang’s outlook on money
- “I wanted to make people feel the emotional weight of international trade.”
- Lang sees the wool coat example in Smith as a powerful symbol of hidden labor and global dependence.
- He believes art can help people see hypocrisy more clearly and rethink how society treats labor, poverty, and wealth.
What the Episode Sets Up
This installment is largely a behind-the-scenes prelude to the premiere of The Wealth of Nations. It ends with Lang about to enter rehearsals with the New York Philharmonic Chorus and orchestra, leaving the audience with the sense that the final meaning of the piece will only become clear once the music is performed in front of a live audience.
