Ezra Klein is an American liberal commentator, journalist, and author. Klein was born and raised in California, and he graduated with a BA in political science from the University of California, Los Angeles. Early in his career, he worked as an independent political blogger before he was hired by The Washington Post to work as a political and economic blogger. He then also wrote for Bloomberg News and MSNBC before leaving to found Vox News along with other veteran journalists in 2014. In 2020, Klein left Vox to serve as an opinion columnist and podcast host at The New York Times, starting The Ezra Klein Show. Klein typically covers politics in his opinion columns, and his podcast also discusses relevant political matters. Klein is the author of the 2020 nonfiction text Why We’re Polarized, which examines how America became politically polarized in the 20th century and how polarization impacts the way Americans view each other and the world around them.
Klein was inspired to write Abundance after he wrote a 2021 column in The New York Times titled “The Economic Mistake the Left is Finally Confronting,” in which he tackled the issue of supply-side economics (also known as “trickle-down economics”) and its negative impacts in the political landscape of the US. The ideas of this essay appear in the introduction of Abundance, when Klein and Thompson illustrate the problems with the bisection of the economy into disparate sides of supply and demand instead of viewing supply and demand from a holistic economic standpoint.
Derek Thompson is an American liberal journalist and podcast host. Thompson grew up in Virginia before graduating from Northwestern University with a triple major in journalism, political science, and legal studies. After college, Thompson became a writer at The Atlantic, where he still works. In 2021, he began his podcast titled Plain English, where he discusses current events, sociology, and modern life. In addition to Abundance, Thompson is the author of two other books. In 2017, he wrote the psychology nonfiction book Hit Makers: The Science of Popularity in an Age of Distraction, in which he explores the psychology of popularity and the economics of the secret markets that shape the US. In 2023, he wrote the philosophical essay collection On Work: Money, Meaning, and Identity, in which he assembled essays he previously wrote in The Atlantic about work, life, and the future of careers and jobs.
Much of Thompson’s work focuses on the economic issues of the US. In his 2022 essay in The Atlantic, titled “A Simple Plan to Solve All of America’s Problems,” Thompson introduced the idea of abundance in the context of America’s supply of healthcare, housing, transportation, and green infrastructure. He built upon his understanding of abundance by working collaboratively with Klein, whom he even quoted in his initial essay, to craft a book focused on applying the ideas of abundance to both the American political and economic spheres. Thompson admits in an interview with The Atlantic that he does not usually put politics first in his writing or podcasting, and his essay about abundance was him “dipping his toes” into the waters of political writing. Working with Klein allowed Thompson to become more politically oriented in his approach to writing and Klein to embrace Thompson’s “forward-looking, sunnier optimism” (Demsas, Jerusalem. “Liberals Can’t Blame Trump for California.” The Atlantic, 18 Mar. 2025).
Katalin Karikó is a Hungarian-American biochemist. She was born in Szolnok and grew up in Kisújszállás, Hungary. Karikó received a BSc in biology and her PhD in biochemistry from the University of Szeged. She continued her postdoctoral research at the Institute of Biochemistry, Biological Research Centre of Hungary. She then came to the US to work, at Temple University and later at the Uniformed Services University of the Health Sciences. Karikó was then hired to work at the University of Pennsylvania to study mRNA. Despite the many possibilities of her research, Karikó was frequently rejected from government-funded grants throughout her career. By 1990, both her career and scientific of mRNA seemed stalled.
Karikó met American immunologist Drew Weissman in 1997, and the two began working together. They co-founded RNARx, and Karikó was the CEO from 2006 to 2013. By the early 2000s, Karikó and Weissman made a breakthrough by creating an mRNA therapy that could enter the cell without wreaking havoc on the immune system. She left academia after continually failing to find traction and support for her research there and in academic publications.
Karikó became vice president and later senior vice president of BioNTech, a German biotechnology company that develops immunotherapies and vaccines, and Moderna and BioNTech researched mRNA for years without releasing a product. The COVID-19 pandemic created an ideal environment to apply mRNA therapies. After Chinese scientists released the genetic sequence of the virus, Moderna’s mRNA vaccine recipe was finalized within 48 hours. Karikó and Weissman won the Nobel Prize in Physiology or Medicine in 2023, finally achieving recognition for their work on mRNA. The two also received other recognitions for their work on mRNA, including the Lasker–DeBakey Clinical Medical Research Award, Time Magazine's Hero of the Year 2021, and the Tang Prize Award in Biopharmaceutical Science in 2022. Karikó returned to Hungary and is currently a professor at the University of Szeged, a position she has held since 2023.
Arthur Laffer is a conservative economist who introduced supply-side economics, a theory that believes reductions in federal taxes will create increased economic growth and, in the long run, increased government revenue. He grew up in Ohio and received a BA in economics at Yale University and an MBA and PhD in international economics at Stanford University. Laffer served as the chief economist for the Office of Management and Budget (OMB) from 1970 to 1972, where his supply-side economic theories gained traction. Laffer’s theories on supply-side economics influenced US economic policy in the 1980s, particularly during Ronald Reagan’s presidency, which became known as Reaganomics.
Laffer created the Laffer curve, which argues that, beginning from a zero tax rate, increases in tax rates will increase the government’s tax revenue; however, at a point when the rates become high enough, further increases in tax rates will create decreased revenue.
Laffer taught at the University of Chicago, the University of Southern California, and Pepperdine University while serving as a political consultant. He was also a US Treasury and Defense Department consultant and President Reagan’s economic policy advisor. In 1979, Laffer founded Laffer Associates, an economic consulting firm. Laffer unsuccessfully ran in 1986 for a US Senate seat as a Republican.
He has served as a financial advisor to politicians and worked on Kansas Governor Sam Brownback’s tax plan. He was an adviser to Donald Trump during his presidential campaign in 2016 and has co-authored multiple books, including Trumponomics: Inside the America First Plan to Revive Our Economy (2018), Return to Prosperity: How America Can Regain Its Economic Superpower Status (2010), and The End of Prosperity: How Higher Taxes Will Doom the Economy—If We Let It Happen (2008). President Trump awarded Laffer with the Presidential Medal of Freedom in 2019.
