An interview with Kenneth Scheve & David Stasavage, authors of Taxing the Rich: A History of Fiscal Fairness in the United States and Europe
Why did you write this book?
KS & DS: Taxing the rich is a subject of considerable political conflict today. There has been a great deal of debate about what government should do in this area, but we know far less about the reasons why some governments actually do tax the rich and others do not. We think answering this question requires a long run historical perspective, and one that doesn’t just look at developments in the United States. Our book considers income, inheritance, and other taxes from 1800 to the present in a set of twenty countries.
What’s your main argument?
KS & DS: Countries tax the rich when the public thinks the state has failed to treat citizens as equals and in so doing has privileged the rich. [a more colloquial version: Countries tax the rich when people think the deck is stacked in favor of the wealthy and the government has done the stacking.]
Debates about taxation revolve around self-interest (no one likes paying taxes), economic efficiency, and fairness. We argue that fairness considerations center on what it means for the state to treat citizens as equals in income tax policy. Historically, there are three main fairness arguments that have been used for or against taxing the rich. Equal Treatment arguments claim that everyone should be taxed at the same rate just like everyone has one vote. Ability to Pay arguments contend that states should tax the rich at higher rates because they can better afford to pay when compared with everyone else. Compensatory Arguments suggest that it is fair to tax the rich at higher rates when it compensates for unequal treatment by the state in some other policy area. We argue that over the last two centuries compensatory arguments have been the most powerful arguments in favor of taxing the rich.
What are examples of compensatory arguments in history?
KS & DS: Compensatory arguments were important in the early development of income tax systems in the 19th century when it was argued that income taxes on the rich were necessary to compensate for heavy indirect taxes that fell disproportionately on the poor and middle class. But the most significant compensatory arguments over the last two centuries have been arguments to raise taxes on the rich to preserve equal sacrifice in wars of mass mobilization. These conflicts, particularly World War I and World War II, led states to raise large armies, often through conscription, and citizens and politicians alike adopted compensatory fairness arguments to justify higher taxes on income and wealth. Mass war mobilization led governments of both left and right to tax the rich.
When have countries taxed the rich?
KS & DS: Well, one thing our book shows is that governments haven’t taxed the rich just because inequality is high, nor have they done this simply because the poor and middle class outnumber the rich when it comes to voting. The main occasion when governments have moved to tax the rich is during times of mass mobilization for war, especially in democracies in which the norm of treating citizens as equals is held more strongly. The real watershed for taxing the rich for many countries came in 1914. The era of the two world wars and their aftermath was one in which governments taxed the rich at rates that would have previously seemed unimaginable.
How do we know that the effect of wars was due to changes in fairness considerations?
KS & DS: We show in the book that when countries shift from peace to war, or the reverse, there has also been a big shift in the type of fairness arguments made in favor of taxing the rich. During times of peace debates about whether it is fair to tax the rich center on competing equal treatment and ability to pay arguments. During times of war supporters of taxing the rich have also been able to make Compensatory arguments. If the poor and middle class are doing the fighting, then the rich should be asked to pay more for the war effort. If some with wealth benefit from war profits, then this creates another compensatory argument for taxing the rich. These compensatory arguments had the biggest impact in democracies that are founded on the idea that citizens should be treated as equals. The fact that war had a much bigger impact on taxes on the rich in democracies than in autocracies also suggests that the rich weren’t being taxed out of simple necessity. It was because war determined what types of fairness arguments could be made.
What are the implications for future tax policies in the United States?
KS & DS: Don’t expect high and rising inequality to necessarily lead to a return to the high top tax rates of the post-war era. What really matters is what people believe about how inequality is generated in the first place. If it is clear that inequality has risen because the government failed to treat citizens as equals in the first place, then there is room for convincing compensatory arguments. Today, in an era where military technology favors more limited forms of warfare — drones rather than boots on the ground — the wartime compensatory arguments of old are no longer available. Absent new compensatory arguments, we expect some to argue for taxing the rich based on ability to pay, but this probably won’t suffice to produce radically higher tax rates. More politically plausible reforms include those that involve increasing taxes on the rich by appealing to the logic of equal treatment to remove deductions, exemptions, and cases of special treatment.
