The thing about this is that the actual top marginal income tax rate is 35 percent. The entire debate in congress over taxes is that President Obama wants to restore the top marginal rate to the level that Dimon thinks it already is. Meanwhile, Dimon doesn't even know what tax rate he pays. Just saying.A couple of things. One is that Dimon was talking about federal taxes, not just federal income taxes, so the payroll tax has to be figured in...but presumably at his income level, that's not going to matter much, since it's gone for most of his income (as are the lower marginal rates that most of us pay on our incomes, which cut the other way for him, for whatever that's worth). And rates on some kinds of income are lower than that top marginal rate. And as Ezra Klein points out, that's before his accountant gets involved. So even if the top rate was what Dimon thinks he's paying, he wouldn't actually be paying that much.
By the way, I'd guess that hardly any people who pay income tax actually know what percentage of their income they pay in taxes, and of course we've seen that there are tons of people who don't even realize they don't pay income tax at all (but do pay payroll taxes). I have no idea whether people in Dimon's cohort even have a good sense of how much money they actually make in a year -- their salaries, sure, they know that, but the rest? I sure wouldn't. All of which is fine, until the start trying to influence public policy based on mistaken notions of their own situation. That, I'd say, isn't apt to produce good results.
And: great catch!
