It’s kind of surprising that, from time to time, the debate seems to resurface of whether or not it’s a good idea to tax the daylights out of those earning unusually high incomes. Yet, an Angry Bear blog post pointed me to an argument it agrees with calling for a millionaire surtax. I have trouble with the piece’s logic.
The argument comes from a blog written by an anonymous economics graduate student hilariously titled “Economists For Firing Larry Summers.” Presumably, its author must find Dr. Summers far too conservative. In the post I care about, the writer attempts to make the case for taxing millionaires much, much more. It relies on an example featuring football star Peyton Manning:
Peyton Manning makes about $30 million a year — let’s explore his potential behavioral responses to changes in taxes. Let’s raise Peyton’s taxes by 10%. Under the logic of Alan Liard, Greg Mankiw’s student, and under the logic that all economists know to be the truth, people respond to incentives. Peyton Manning is a person, so he responds to this tax hike by working 6% less, and decides now he’s going to sit for the Colts playoff games since he makes less money per game, and he enjoys watching Tom Brady play in the playoffs more than being there himself. Doesn’t really sound likely, does it?
Of course, the mistake here is that that the author fails to fully understand how incentive works more broadly. If you don’t believe in incentive, then the logic he’s using probably makes perfect sense. So does socialism.
But if you do believe in incentive, and in capitalism, then you know that incentive can produce innovation, progress and economic growth. What I think the author is trying to get at is — even if you have a surtax on millionaires, they’ll still be motivated to excel if they’re making relatively more money than others. I don’t think the writer is arguing for egalitarianism so much as a much more progressive tax code. But I still think the author is wrong.
First, the question, I think, is how progressive such a tax would have to be to matter. I completely agree that in his example above, a 10% higher tax rate probably wouldn’t hurt incentive all that much. But 10% higher taxes for millionaires also wouldn’t produce all that much more tax revenue, which is presumably why you would tax them more. In order to collect a truly substantial amount more from millionaires, you’d have to raise their taxes by more than a few mere percentage points — there aren’t that many of them.
So, really, the example above might not be a big problem, but it also isn’t a solution. You need much higher marginal rates. Yet, the author doesn’t appear to be entirely comfortable with this, as writer isn’t completely unaware of incentive:
But then, you might object, *nobody* would have an incentive to become CEO if their salaries are capped around $1 million (if I was designing a tax system, I would probably not go over 50% on taxes before $3-4 million, but I would make Peyton Manning’s marginal rate closer to 70%…)
Here’s the problem: a much more progressive tax code still hampers incentive — even without any pure caps. Let’s imagine that millionaires taxes were raised by, say, 30% across the board, as he envisions. You have to go back further in the development of Peyton Manning than the author does in the example to really understand a surtax’s effect on innovation and economic growth. The problem is that there might not be anyone to replace Manning, because from a very early age, young football players might not have had enough motivation to excel.
Let’s generalize the example and ditch the football. Imagine you’re a kid, growing up in a lower- or middle-class family. The higher the tax on millionaires, the less reason you’ll have to work your hardest in school, get into the best college, and eventually get a job that could produce the most economic growth. After all, you might do all that work and still end up in a mediocre job, stuck in the middle class, no matter how hard you work. Natural talent and luck also have something to do with it.
The point is that ambition is a high-risk behavior. When you choose to work hard in school instead of partying, endure tens or hundreds of thousand dollars in loans to go to a top college, and/or sacrifice spending more time with your family to get that promotion, you’re making tough choices. Those easier alternatives look pretty attractive, particularly since you can’t be certain that the harder ones will lead to a better life or one day as a millionaire. Gliding through life is definitely an attractive path, so you’re taking a big risk by being so ambitious. I don’t know of any study to back me up, but I’d hypothesize there’s a strong correlation between ambition and low risk aversion for exactly this reason.
And as the author surely knows by studying economics, you should only take a huge risk if there’s a proportionally large reward that could follow. You wouldn’t invest $50,000 in a company with equally likely possible outcomes of losing all your money or making $2,500 profit. You might if that potential profit was $250,000 Similarly, you aren’t going to work hard throughout your early life and in your career if your earnings can never have the potential justify that sacrifice.
So where’s that line? 40% tax? 70% tax? I’m not sure. But the legitimate fear is that if taxes on income are raised to too high a level, then innovation and progress might suffer. The higher the taxes on the rich, the less reward for living an ambitious life.
