“We are the 99 percent” is a great slogan. It correctly defines the issue as being the middle class versus the elite (as opposed to the middle class versus the poor). And it also gets past the common but wrong establishment notion that rising inequality is mainly about the well educated doing better than the less educated; the big winners in this new Gilded Age have been a handful of very wealthy people, not college graduates in general.

If anything, however, the 99 percent slogan aims too low. A large fraction of the top 1 percent’s gains have actually gone to an even smaller group, the top 0.1 percent — the richest one-thousandth of the population.

And while Democrats, by and large, want that super-elite to make at least some contribution to long-term deficit reduction, Republicans want to cut the super-elite’s taxes even as they slash Social Security, Medicare and Medicaid in the name of fiscal discipline.

Before I get to those policy disputes, here are a few numbers.
The recent Congressional Budget Office report on inequality didn’t look inside the top 1 percent, but an earlier report, which only went up to 2005, did. According to that report, between 1979 and 2005 the inflation-adjusted, after-tax income of Americans in the middle of the income distribution rose 21 percent. The equivalent number for the richest 0.1 percent rose 400 percent.
For the most part, these huge gains reflected a dramatic rise in the super-elite’s share of pretax income. But there were also large tax cuts favoring the wealthy. In particular, taxes on capital gains are much lower than they were in 1979 — and the richest one-thousandth of Americans account for half of all income from capital gains.

Given this history, why do Republicans advocate further tax cuts for the very rich even as they warn about deficits and demand drastic cuts in social insurance programs?

Well, aside from shouts of “class warfare!” whenever such questions are raised, the usual answer is that the super-elite are “job creators” — that is, that they make a special contribution to the economy. So what you need to know is that this is bad economics. In fact, it would be bad economics even if America had the idealized, perfect market economy of conservative fantasies.

After all, in an idealized market economy each worker would be paid exactly what he or she contributes to the economy by choosing to work, no more and no less. And this would be equally true for workers making $30,000 a year and executives making $30 million a year. There would be no reason to consider the contributions of the $30 million folks as deserving of special treatment.
But, you say, the rich pay taxes! Indeed, they do. And they could — and should, from the point of view of the 99.9 percent — be paying substantially more in taxes, not offered even more tax breaks, despite the alleged budget crisis, because of the wonderful things they supposedly do.

Still, don’t some of the very rich get that way by producing innovations that are worth far more to the world than the income they receive? Sure, but if you look at who really makes up the 0.1 percent, it’s hard to avoid the conclusion that, by and large, the members of the super-elite are overpaid, not underpaid, for what they do.

For who are the 0.1 percent? Very few of them are Steve Jobs-type innovators; most of them are corporate bigwigs and financial wheeler-dealers. One recent analysis found that 43 percent of the super-elite are executives at nonfinancial companies, 18 percent are in finance and another 12 percent are lawyers or in real estate. And these are not, to put it mildly, professions in which there is a clear relationship between someone’s income and his economic contribution.
Executive pay, which has skyrocketed over the past generation, is famously set by boards of directors appointed by the very people whose pay they determine; poorly performing C.E.O.’s still get lavish paychecks, and even failed and fired executives often receive millions as they go out the door.

Meanwhile, the economic crisis showed that much of the apparent value created by modern finance was a mirage. As the Bank of England’s director for financial stability recently put it, seemingly high returns before the crisis simply reflected increased risk-taking — risk that was mostly borne not by the wheeler-dealers themselves but either by naïve investors or by taxpayers, who ended up holding the bag when it all went wrong. And as he waspishly noted, “If risk-making were a value-adding activity, Russian roulette players would contribute disproportionately to global welfare.”

So should the 99.9 percent hate the 0.1 percent? No, not at all. But they should ignore all the propaganda about “job creators” and demand that the super-elite pay substantially more in taxes.
