Talking Again With Gabriel Zucman

For all my interviews and more, subscribe on YouTube.In my writing about wealth concentration and oligarchy, I steal a lot from lean heavily on the truly work of Gabriel Zucman, who is a hugely important researcher (winner of the 2023 Clark Medal) who is also starting to play a major role in policy. I’ve talked to him before, but this seemed like a good time to bring him back.. . .TRANSCRIPT: Paul Krugman in Conversation with Gabriel Zucman(recorded 7/23/26)Paul Krugman: So, hi everyone. Paul Krugman here, bringing back Gabriel Zucman, probably the best guy for thinking about inequality, especially wealth issues. And since I’ve been writing about that and stealing a lot of Gabriel’s research, I thought we should talk again. So, hi Gabriel.Gabriel Zucman: Hi Paul, thanks for having me on.Krugman: Yeah. So, you have been writing—and now I’ve been, you know, cannibalizing it—a lot about wealth concentration. Why don’t you tell us about your reasons for focusing on wealth.Zucman: Basically, because there’s a fundamental tension in democratic societies between extreme wealth and the very possibility of a well-functioning democracy. And it’s not a new idea—don’t get me wrong. All the thinkers of democracy have written about this, all the way back to Aristotle, more than two thousand years ago.Krugman: Right.Zucman: But there was a period of time after World War II when many people thought that this issue belonged to the past. And it corresponded to a very particular moment in history when extreme wealth had largely disappeared after World War II, after the shocks of the first half of the twentieth century.But now, of course, it’s making a dramatic comeback. And so we are back to this discussion of: how do we deal with this tension? How do we organize the economy and our society to prevent the forms of capture of the political process, in particular, that are associated with extreme wealth?Krugman: Now, there’s a question. I mean, I’ve been on the inequality beat for an alarmingly long time—since you were a small child, actually. But in the early nineties, let’s say, it was all income rather than wealth. And a lot of it was top quintile, and maybe top one percent. And now you’re telling us that we need to focus on the wealth rather than the income of the top 0.0002 percent. Why that shift? Why wealth rather than income?Zucman: Well, it’s for two reasons. Number one is a macroeconomic reason, which is that wealth as a whole has been growing much faster than income. So if you look at the ratio of total household wealth to GDP in the US in 1980, it was around 200–250%, and today we are past 500%. This means that the total wealth of the country is equivalent to more than five years of annual production, five years of annual GDP. The second reason is that wealth itself has become much more concentrated, and the rise of wealth inequality, especially at the top of the distribution—at the very top—has been massive and has been even faster and stronger than the rise of income inequality.So we all know about the rise of the top one percent; the top one percent’s share of total income has increased from about ten percent of income in the US in 1980 to about 20% today. But at the top of the wealth distribution, the increase has been even much more dramatic than that.Krugman: At the risk of derailing it slightly, one thing that I myself have gone back and forth on—and certainly I get from comments on things I write—is a question comparing the wealth of the top 0.001%, or whatever: should we be comparing it to total wealth or to total income? And I know you’ve used wealth to GDP, and I have some thoughts, but you’ve done it both ways. Which do you use, and why would you use it? I don’t know which is right, but what are your thoughts?Zucman: I think both statistics are interesting and capture different aspects of reality. So if you’re interested in wealth inequality, in the concentration of wealth, the most meaningful statistic is to divide the wealth of the super-rich by total wealth in the economy. So, for instance, if you look at billionaires—roughly the top 0.1 percent of the population—they own about seven percent of total US wealth today. In 1980, they used to own about one percent of total US wealth. So it gives you a sense of the rise in wealth concentration. If you look at the super-top,
