"Somebodies"?! You're right, there are more important things than weight to ridicule. Hie thee to a dictionary.
The point is, Brad is not "somebody"; he's "Somebody." He's one of those Council of Economic Advisers-caliber economists who are called on to sanction national policy and, in times of austerity, tell the people to "pull in their belts," etc. This appeal is more seemly (at least) when it comes from cadaverous types like Alan Greenspan or Robert Rubin (whatever their myriad other limitations) and not porkers like DeLong or Larry Lindsey. Being in the public eye in such a capacity imposes some responsibility for not being a symbolic hypocrite.
