"Former President Truman used to have a phrase that described pretty accurately the position of the man at the head of a business. "The buck stops here," the President used to say, pointing at his own desk. What he meant was that others could pass along the burden for a decision made, or to-be-made, but the man at the top had nowhere else to pass it. The "buck" stopped there."
