Between 2002 and 2007, for instance, the bottom ninety-nine per cent of incomes grew 1.3 per cent a year in real terms—while the incomes of the top one per cent grew ten per cent a year. That one per cent accounted for two-thirds of all income growth in those years. People in the ninety-fifth to the ninety-ninth percentiles of income have represented a fairly constant share of the national income for twenty-five years now. But in that period the top one per cent has seen its share of national income double; in 2007, it captured twenty-three per cent of the nation’s total income. Even within the top one per cent, income is getting more concentrated: the top 0.1 per cent of earners have seen their share of national income triple over the same period. All by themselves, they now earn as much as the bottom hundred and twenty million people. So at the same time that the rich have been pulling away from the middle class, the very rich have been pulling away from the pretty rich, and the very, very rich have been pulling away from the very rich.
The current debate over taxes takes none of this into account. At the moment, we have a system of tax brackets well suited to nineteenth-century New Zealand. Our system sets the top bracket at three hundred and seventy-five thousand dollars, with a tax rate of thirty-five per cent. (People in the second-highest bracket, starting at a hundred and seventy-two thousand dollars for individuals, pay thirty-three per cent.) This means that someone making two hundred thousand dollars a year and someone making two hundred million dollars a year pay at similar tax rates. LeBron James and LeBron James’s dentist: same difference.
This makes no sense—there’s a yawning chasm between the professional and the plutocratic classes, and the tax system should reflect that. A better tax system would have more brackets, so that the super-rich pay higher rates. (The most obvious bracket to add would be a higher rate at a million dollars a year, but there’s no reason to stop there.) This would make the system fairer, since it would reflect the real stratification among high-income earners. A few extra brackets at the top could also bring in tens of billions of dollars in additional revenue.
Definitely. Read the rest. Predictably, Megan McArdle feels the wealthy are terribly persecuted (and Roy's comment thread is good, as usual).
