TranscriptLisa Kiefer: [00:00:03] This is method to the madness, a biweekly public affairs show on K-A-L-X Berkeley celebrating Bay Area innovators. I'm your host Lisa Kiefer. And today I'm speaking with Gabriel Zucman Professor of Economics and Public Policy here at UC Berkeley. He has just co-authored a book with Emmanuel Saez called The Triumph of Injustice --How the Rich Dodge Taxes and How to Make Them Pay. Welcome to the program, Gabriel.Gabriel Zucman: [00:00:36] Thanks for having me.Lisa Kiefer: [00:00:37] Why did you write this book. What was the problem or problems you were trying to solve?Gabriel Zucman: [00:00:42] So the main problem is the rise of inequality in the US. So if you look for instance at what has happened to income concentration, in 1980, the top 1 percent highest earners in the U.S. earned about 10 percent of total U.S. national income today they earn 20 percent of U.S. national income. Now contrast that with what has happened for the working class for the bottom 50 percent of earners. They used to earn 20 percent of income and now about 12 percent. So essentially the top 1 percent and the bottom 50 percent have have switched their income share. And the reality of the U.S. today is that the 1 percent earns twice as much income in total than the bottom 50 percent a group that by definition is 50 times larger. So you have this huge level of inequality and this big increase in inequality and the tax system is a key institution to regulate inequality. And so we wanted to know OK does it do a good job? Does the tax system limit inequality or does it exacerbate the rise of inequality?Lisa Kiefer: [00:01:58] And as you say in your book all the way back to James Madison the whole point of taxes yes is to raise revenue but the other significant point was to reduce inequality.Gabriel Zucman: [00:02:07] Exactly.Lisa Kiefer: [00:02:08] And that's something that's been kind of forgotten since 1980.Gabriel Zucman: [00:02:11] That's been forgotten despite the fact that it's deeply rooted in American society. The U.S. was created in large part in reaction against the highly unequal aristocratic societies of of Europe in the 18th century and ever since, many people in the US have been concerned about becoming as unequal as Europe. Europe for a long time was perceived as as an anti model, too unequal, at least until the middle of the 20th century. Now it's the opposite, it's funny to see how these beliefs and perceptions have changed over time. Now many people in the US feel that Europe is too equal, but in fact for most of US history it was it was the opposite. The US invented some of the key progressive fiscal institutions designed to limit inequality to regulate inequality. Let me just give one example. In 1943 Franklin Roosevelt goes to Congress. He makes a famous speech. He says I think that no American should have an income after paying taxes of more than twenty five thousand dollars which is the equivalent of a few million dollars today. Therefore I propose to create a top marginal income tax rate of 100 percent above twenty five thousand dollars. And that's the idea of a legal maximum income. That's an American, a Roosevelt invention. And people in Congress they hesitate a little bit you know 100 percent, maybe it's too much, but they agree on 93 percent which when you think about it is that very far from 100 percent. And then the U.S. kept these very high modern 90 percent top marginal income tax rates for a long time. So there is this deeply rooted tradition in the U.S. of using the tax system to limit the concentration of income. The idea being that wealth is a good thing for the working class, for the middle class. It provides safety, provides security. But for the very rich,wealth is not safety or security. Wealth is power. And an extreme concentration of wealth means an extreme concentration of power, of political power, of economic power, which is detrimental to the rest of society and so one key function of the tax system is to prevent such a concentration of wealth and such a concentration of power from happening.Lisa Kiefer: [00:04:52] You've been consulting with Elizabeth Warren and others adopting pieces of some of the ideas that you had. How does Elizabeth Warren's plan, when you plug it into your model in the book, your 1980 model,what was the outcome of plugging in her wealth tax.Gabriel Zucman: [00:05:09] So Elizabeth Warren proposes to create a wealth tax at a rate of 2 percent above 50 million dollars and 6 percent above 1 billion dollars. So just let me explain what this would do. It means that if you have 50 million dollars in wealth or less, you pay zero. One of the things we do in the book we tried to imagine how the U.S. economy would have looked like if such a tax had been in place since 1982. So let me first start with what has happened to wealth concentration since 1982. If you look at the 400 richest Americans, you know Forbes magazine ...
