"Seven hundred billion was a number out of the air," [Neel] Kashkari recalls, wheeling toward the hex nuts and the bolts. "It was a political calculus. I said, 'We don't know how much is enough. We need as much as we can get [from Congress]. What about a trillion?' 'No way,' Hank [Paulson] shook his head. I said, 'Okay, what about 700 billion?' We didn't know if it would work. We had to project confidence, hold up the world. We couldn't admit how scared we were, or how uncertain." Well. Ain't that grand.
