That’s the kind of stimulus, David Brooks reminds us, that the the president’s leading economic expert--the brainy Larry Summers--said we should believe in. What the House passed is none of the above--an undisciplined mess of jarring elements that will be worse than useless. Somebody might say that, of course, the Democratic Congress isn’t going to include an exit strategy from bigger government. But it’s also true that such self-indulgent packages are just characteristic of Congress, although, of course, never before on this scale. In this case, arguably, the cure might have been the executive leadership of a smart and popular president--with the help of his excellent expert.
