Desperately seeking middle-class taxes

Think about his logic like this: Mr. Ryan’s House budget details a long-range plan to equalize spending and tax revenues without—ahem—raising tax rates. But if such fiscal restraint is as deep and draconian as Mr. Obama claims, then as a matter of arithmetic the White House must favor a tax increase of an equal size, or something close to it, in order to pay for the amount of government he wants to sustain. …

Mr. Ryan’s major contribution has been to expose the illusion that Mr. Obama’s re-election campaign rests on: pretending that raising taxes on a few thousand “millionaires and billionaires” can fund an ever-growing government. …

The researchers looked at how high income-tax rates would have to rise in the top two or even three tax brackets to lower debt to sustainable levels under something akin to CBO’s alternative fiscal scenario. They conclude that even if the top rates hit 100%, the budget “cannot achieve the debt-reduction targets in some or any of the target years.” Though conceding that near-total confiscation is “completely unrealistic,” they report the results anyway “to indicate the infeasibility of achieving a high debt-reduction target simply by increasing top individual income tax rates.” And this is from economists who favor higher taxes.

Another way of putting it is that the rich aren’t nearly rich enough to finance Mr. Obama’s spending ambitions. Sooner rather than later, Washington will come for the middle class, because that’s where the real money is.
