It is hard to imagine McCain’s economic arguments becoming any dumber or more deceptive, but that’s not stopping his campaign from trying. Appearing on Hardball, McCain surrogate Tom Ridge – dutifully hawking McCain’s “Obama wants to spread the wealth” meme — told Matthews that Barack Obama’s willingness to “spread the wealth” meant that he would impose a "ceiling" on the ability of Americans to "achieve their aspirations."

McCain and Palin have been trolling a bait and switch version of this, implying that if Joe the Plumber would be taxed to spread the wealth, then all ordinary Americans would be faced with confiscation to help the undeserving poor, using the "IRS as a welfare agency." Never mind that the claim is totally false.

Ridge took the argument a step further, though he surely knew he was talking absolute gibberish. If there were literally such a "ceiling," it would mean that the marginal tax rates would rise to 100 percent for all income over $250,000, but of course, Obama’s proposed tax rates for the wealthiest would simply return to what they were during the Reagan/Clinton Administrations and would thus rise only slightly over what they are today.

But that fact did not stop Ridge from playing the idiot on McCain’s behalf. Matthews explained that taxing the wealthy at higher rates than the less wealthy had always been deemed fair, because unlike most Americans, the wealthiest could afford higher tax rates and still live extremely well; taxes were thus “progressive” for a valid reason.

Matthews then asked Ridge whether he opposes progressive tax rates? Ridge tried to dodge, refusing to say he opposed progressive taxes in principle. But he insisted it was objectionable for Obama to articulate the concept in the middle of a campaign.

So the approved McCain claim this week is that even if progressive taxes are okay in concept, it’s wrong for a candidate to explain to voters this means wealthy people should pay taxes at a higher rate than non-wealthy people. And McCain’s audiences usually applaud when they hear McCain equate such proposals to "socialism."

Barack Obama responded Monday in Florida:

It’s true that I want to roll back the Bush tax cuts on the wealthiest Americans and go back to the rate they paid under Bill Clinton. John McCain calls that socialism. What he forgets is that just a few years ago, he himself said those Bush tax cuts were irresponsible. He said he couldn’t "in good conscience" support a tax cut where the benefits went to the wealthy at the expense of "middle class Americans who most need tax relief." Well, he was right then, and I am right now.
