Over the weekend, the White House leaked word that President Obama will push a new debt-reduction idea: the “Buffett Rule.” Named after Warren Buffett, the chairman and chief executive of Berkshire Hathaway, who’s been urging policymakers to raise taxes on the very wealthy. As Buffett recently explained, millionaires and billionaires “have been coddled long enough.”

We don’t yet know the details of the proposal — most notably, what the new millionaires’ minimum tax rate would be — but Republicans are already responding with predictable disgust.

Here, for example, was House Budget Committee Chairman Paul Ryan (R-Wis.) yesterday on Fox News, making the case for coddling millionaires and billionaires for a while longer. See if you can pick up on the subtlety of his talking points.

“Class warfare, Chris, may make for really good politics but it makes a rotten economics. We don’t need a system that seeks to divide people. […] “[I]t looks like the president wants to move down the class warfare path. Class warfare will simply divide this country more. It will attack job creators, divide people and it doesn’t grow the economy. […] “[I]f we are just going to do class warfare and trying to get tax increases out of this, and I don’t think much will come of it…. He’s in a political class warfare mode and campaign mode.”

So, I guess I’ll put him down as a “maybe” on the Buffett Rule?

By any reasonable measure, Ryan’s arguments aren’t just wrong, they’re borderline offensive.

For a generation, Republican policymakers have rigged national tax policy to reward the wealthy, and then reward them some more. We’ve seen the class gap reach Gilded Era levels, only to hear GOP officials again demand that working families “sacrifice” while lavishing more breaks on the very wealthy.

Remind me, who’s engaged in “class warfare” and “dividing people”?

Also note the larger policy context here. President Obama wants the richest of the rich to pay a little more, but keep tax breaks in place for the middle class. Paul Ryan and his cohorts want the polar opposite — more breaks for the very wealthy and higher taxes for the middle class.

Let’s also not forget that one of the GOP’s more common tax-policy arguments is that nearly half the country doesn’t have any federal income tax burden — and they see that as a problem that needs fixing. As a practical matter, the Republican argument on this is practically the definition of “class warfare.”

I realize much of the political establishment has come to look at Paul Ryan as a wise wonk who deserves to be taken seriously, but it really doesn’t take much to realize how spectacularly wrong the far-right Wisconsinite really is.
