That would be Ben Bernanke, who by his own claim brought us to the edge of a second Great Depression. The Post told readers that Bernanke:

“has aimed to use the weight of his words to try to give more momentum to efforts to reduce the budget deficit in the medium to long term.”

It would have been reasonable to note the irony that a person who failed so miserably at his job — causing tens of millions to be unemployed or underemployed, and also causing deficits to soar — would lecture Congress and the public about deficits.
