Now, when anybody starts talking about this [an all-volunteer force] he immediately shifts language. My army is 'volunteer,' your army is 'professional,' and the enemy's army is 'mercenary.' All these three words mean exactly the same thing. I am a volunteer professor, I am a mercenary professor, and I am a professional professor. And all you people around here are mercenary professional people. And I trust you realize that. It's always a puzzle to me why people should think that the term 'mercenary' somehow has a negative connotation. I remind you of that wonderful quotation of Adam Smith when he said, 'You do not owe your daily bread to the benevolence of the baker, but to his proper regard for his own interest.'
