Former economist Paul Krugman has actually managed to get these words past an editor at the New York Times:
There is, however, one big difference between corporate persons and the likes of you and me: On current trends, we’re heading toward a world in which only the human people pay taxes.
Now I think we can be quite sure that even Paul Krugman, with his gargantuan capacity for forgetting everything he once knew, is well aware that we already live in a world where only human people pay taxes. That’s an instance of the general principle that the legal incidence of a tax does not determine its economic incidence. The corporate income tax is levied by law on corporations, but its economic effects are felt entirely by humans.
Why then, did he write this in the first place? Well, the charitable reading — and I am all in favor of charitable readings — is that all he’s saying is that the legal incidence of taxation has shifted somewhat from corporations to individuals.
But why would that be interesting? And why would it be, as Krugman seems to take for granted, a clearly bad thing? Suppose that in 1990, I received a $1 dividend and paid a 25% tax, keeping 75 cents in my pocket, while in 2014, due to a fall in corporate rates (leading to higher dividend payouts) and a rise in personal rates, I received a $1.50 dividend and paid a 50% tax, keeping 75 cents in my pocket. Who cares?
Well, perhaps there are reasons to care, involving some non-obvious incentive effect of the sort that it takes an economist to notice. Well, that, then, is where the economist comes in — his job being to explain why he thinks these things matter. In this case, I don’t offhand see the argument, but I’m perfectly happy to believe there might be one. On the other hand, if Krugman actually has an argument in mind, one wonders why he’s so reluctant to share it.
Oh, he does pay lip service to the need for an argument, but all he offers is sophistry:
