The Pacific Standard reports on Duncan Black, who blogs under the name Atrios. According to the Pacific Standard, Atrios has introduced into the political marketplace the startling notion of increasing Social Security benefits.
For obvious reasons, I like to think that bloggers can make a difference. However, I'm not sure that the notion of increasing Social Security benefits was ever a completely unknown idea or that Atrios has moved that idea closer to becoming reality. Over the years I've often heard those on the left saying that Social Security benefits should be increased, not cut. Those views were on the periphery. I'd say they remain on the periphery. Time will tell whether this idea really moves into the mainstream.
My gut feeling is that Atrios is simply responding to the larger theme that long term demographic trends strongly favor the Democratic party and liberal policies in general. If events unfold as this theory holds, the Republican party, as currently constituted, would lose almost all of its power over the next ten to fifteen years. Would Social Security be increased if this comes to pass? Maybe. It's just too far off to tell.
