I guess Byron Tau thought he had to make it look like Big Labor is really, really mad at President Barack Obama and the White House so he could make Obama look like he's a moderate on economic and fiscal issues. Thus his Sunday morning post's headline: "Labor targets Obama over proposed benefit cuts."
Of course, they aren't "cuts" at all, though they are being portrayed as such. All Obama has done, according to information which appears to have been conveniently leaked (perhaps in hopes of killing the idea) to the New York Times ahead of his very late President's Budget, is "propose a new inflation formula that would have the effect of reducing cost-of-living payments for Social Security benefits, though with financial protections for low-income and very old beneficiaries, administration officials said." Despite the weakly descriptive language at the Times, monthly Social Security and other checks would continue to increase under the proposal each year inflation occurs -- just not by as much.
