[C]onservatives are right to believe that Romney isn't to be trusted. Sure, he lowers tax rates on millionaires by 9 percentage points, and you may think that's a pretty sweet deal for the rich. But come on. Newt Gingrich would lower them by 24 percentage points. (No, that's not a typo.) Rick Perry lowers them by 20 percentage points. Herman Cain lowers them by 15 points. Frankly, Romney is hardly even trying here.

THE Tax Policy Center has completed an analysis of the distributional effects of Mitt Romney's tax plan , and as might be expected it's quite good for you if you're raking in the big bucks, and not particularly helpful if you're not. For the bottom 80% of the income distribution, federal tax rates would drop between 0.6% and 3.4%. For the top 20%, they'd drop 5.9%; for the top 1%, they'd drop 8.6%. That means the regular-joe taxpayer at the middle of the distribution gets a cut of about $1,400, while a taxpayer in the top 1% gets a cut of $171,000. Kevin Drum cracks wise

Along similar lines, and because I've been reading about this stuff lately, I'd like to point out that in the long historical context the tax rates Mr Romney is proposing are still extremely progressive. In fact, up until at least the 15th century or so, tax rates in the Western world were generally higher for poor people than they were for rich people. In early Renaissance Florence, as Tim Parks explains in his highly readable "Medici Money", almost all state revenues were raised from excise taxes on consumption, while the holdings of the wealthy were exempt from almost any form of routine taxation. This state of affairs persisted until 1427, when the cost of hiring mercenaries to protect the city from the Duke of Milan, the French, and basically everyone else in the free-for-all of Italian politics rose so high that they had to introduce a universal tax called the catasto. This exempted about a third of the poorest households, while everyone over a certain level of income had to pay a flat tax of 0.5% on their wealth—a wildly progressive move in its day.

Meanwhile in Flanders, as John Munro writes in "The Usury Doctrine and Urban Public Finances in Late-Medieval Flanders (1220-1550): Rentes (Annuities), Excise Taxes, and Income Transfers from the Poor to the Rich", state finance came to rely increasingly on issuing annuities paying an annual income. This was because the Catholic church's rulings on usury made it increasingly difficult for sovereigns to borrow at interest. The Pope said it was okay to issue the annuities as long as the taxes used to pay them came from the produce of the land, safely removing them from the unnatural auto-reproduction of money implied in usury. That meant, again, that taxation mainly consisted of excise taxes on consumption, and "the obvious significance of this form of public-finance related taxation was that it was essentially very regressive, in representing a far greater burden on the poor than on the middle classes, let alone the rich." Since most people who could buy and hold state annuities were rich, it was a pretty direct transfer of wealth from the poor to rentiers.

So, again, while it's true that Mr Romney's tax plans represent a large net transfer from the poor to the rich if you start from the baseline of current tax law, they're actually pretty progressive if you're willing to start from a pre-modern baseline.
